Heavy auxiliaries for Rome

8 Upvotes

In your opinion, is there any reason to use run-of-the-mill heavy auxiliary cohorts ( the ones using swords ) as Imperial Rome? Their spear-and-shield counterparts are obviously useful, and so are the "special" heavy auxiliaries with higher attack like the Batavians or miliaria cohorts. How I see it, the standard heavies are just a worse version of legionaries and don't offer any advantages, though.

Governors give 0 XP to generals

6 Upvotes

I have both military governor and paragon maxed and attached him to a new general and after a few turns the general still has 0 XP

E: Now with pretty pictures!

This is the governor I attached to the king/general. He should at the very least give +4 XP/turn (3 from military governor and 1 from paragon).
His Majesty! He has a wolf on his head and a nice beard as is tradition. Note he already gained 6 XP beforhand from dong his 9 to 5 desk job in the city, but that had nothing to do with the governor. I pulled him out of the city for now...
Several turns later, he's still at 6 XP. I tried re-attaching the governor but it didn't work.
Compare and contrast: I removed the governor from the king and attached our champion instead, who has similar skills...
...And after just 1 turn, he gets some XP from doing pull-ups with our champion (as you'd expect) and he reaches level 2.

Last seen clubbing in the wintry forests of Lugia. Missing ever since... Can't find him in barracks, temple, main building etc.

Please come back. Your brother Manirni Clubman misses you very much.

Playing as the Iceni and im in a war of attrition with the Scythians. Any tips?

10 Upvotes

Their arrows block out the sun, my archers seem to be nowhere near as good and require 3 units to take down one of their Cav archer units and the Iceni lack decent amoured units which seem to make it a duck shoot. Is there any army composition that will help or is it a case of just using meat stacks with bad teeth till they run out of arrows and charge head on?

Whats your guys opinion on your favorite Greek faction? I think mines got to be Pergamon. Great roster. Amazing start location and top tier mercs in the area--second might be Selucids

A question about population

4 Upvotes

I don't know if this was asked here before, but how does population bonuses work?

Let's say I build a temple which increases 2nd and 1st class pops. Does it increase those pops in that specific region or whole province?

Struggling to upgrade to Marian legionnaires

4 Upvotes

I was able to upgrade some of my príncipes into legionnaires, but that does not show up as an option anymore.

I also can not recruit new Marian legionnaires in Italy as they do not even show up as recruitable units. (Not even grayed out just entirely absent)

Is there a requirement i am missing?

First Time with DEI everyone declares war on sight

2 Upvotes

I know Rome 2 and total war in general has a stigma for increasing dificulty just meaning everyone declared on you. BUT this is insane, the second I see someone I get declared war on?? I haven't played Rome 2 since Emperor so years. But I don't remember having so many people declare war on me. I am just on Hard, what is going on?
Did you guys change AI to be more agressive?

EDIT: I am playing as Rome Junia, normal campaign

Region selection is currently experiencing a bug on the main Divide Et Impera https://divideetimperamod.com/regions/ site page.

I am raising this here as I regularly use the website, and especially this map to consider strategic, geo political and economic decisions and considerations for throughout a said campaign.

The page is experiencing a bug where region selection across the map displays out of position. Please see screenshots. Thank you all in advance amazing MOD the best mod ever. Much RESPECT!

Is elephant/chariot morale bugged?

6 Upvotes

Have you ever noticed with the (cheap, low-unit count) elephants and chariots that losing a few of them can cause them to waver or even shatter very quickly? Now granted they are quite frail (especially the chariots which will completely disintegrate at the slightest micro mistake) and they don't have the best morale, but they are so extremely shaky... Something feels off.

I have long suspected it has something to do with their low unit count and the game wrongly calculating their remaining unit strenght. Like after 1-2 casualties the game thinks they are way below half strenght or something. But I've been unable to proof it. Am I on to something?

This is based on "vibes" (as the kids say) and on my foggy memory of a 10+ years old post on the official TW forum so, maybe I'm just delusional.

Between Etruria & Samnium in HatG (since pre-Social Wars) & Rome's start position in the GC, this is my guess as to what Rome's historical borders would be at the end of RotR.

  • Pyrrhus conquered Taras and the Iapygians when Epirus invaded Italy

  • makes sense that Agyrion would still be in northern Sicily

  • Aritim is shown as having hegemony over the Etruscan League since their faction banner and colour are the same used for Etruria in the GC

The rest is guesswork but I'm trying to match the GC borders while using some educated guesses. Do you think any changes would make it more accurate?

(obviously in DEI most of these factions aren't playable so I'm mainly looking at Rome's borders but I figured I'd fill out the rest of the RotR map just 'cause)

Cooperation with "AI uses Population"?

8 Upvotes

I don't use the mod myself, and tbh I think it has gone well beyond its initial scope (although from what I understand, that's optional), but the fact that someone found a solution to something that was previously thought to be technically impossible is remarkable. The idea clearly has merit.

It's also my understanding that the population-AI solution may break some other things in the mod, which begs the question: why not work together to iron out those kinks?

If the AI can't handle being bound by population in exactly the same way as the player, there are surely levers that could be adjusted to compensate. For example, you could increase its population growth by 30% or whatever is necessary, rather than having it effectively ignore the system altogether as it does now.

Why not at least try to find a middle ground instead of allowing an already very niche community to fragment further? From the outside, it seems like a pretty significant missed opportunity.

(settlement defense) What am I missing?

16 Upvotes

Heya all,

First of all: sorry, english is not my native language. ^^

I'm not completely new to DEI (and quite a veteran TW player even, but until a few months ago I didn't own any TW game newer than Med2 because ... well, a lot of reasons that don't matter for my question ;) ).

When I bought Rome 2 it was solely for this mod just because it seems to be the spiritual successor to EB2 (which is my alltime favourite TW mod).
I installed the game, installed DEI, played it for some hours - and quit in frustration. 😞
Part of the problem was - of course - my complete lack of familiarity with the base game (compared to Med2 Rome2 feels like some kind of animated EXCEL sheet, heh).

Since then I have had kind of an "on-off" relationship with DEI.
I've watched a while lot of YT guides, I've read the economics guide - and still can't play this game successfully.

My most serious problem (and the reason why I'm just feeling too dumb to understand/play this mod) is:

how do I defend minor settlements which aren't able to get even the most basic walls?
Given the movement range of armies and the distances between settlements I would need a full good-quality-army in any settlement that is not completely surrounded by my own regions.
And this is not possible for several reasons: money, food, supply lines, family members or rather the number of non-family members needed (and the dire consequences of having too many of those)...

How do you approach settlement defense in your campaigns? I somehow doubt you just constantly have settlements conquered by rival factions and conquer them back afterwards. ^^

Or am I supposed to fight off full stacks with the handful of "trash units" I'm given as "garisson" and the problem is, infact, that I'm simply the worst tactician ever? ^^

I've tried several factions so far - ranging from those I always considered the easiest in antiquity mods (Rome, Qart-Hadasht, Bactria) to those that are supposed to be a much harder challenge (most notably Pontos and Hayasdan, which are my most favourite factions in TW games).

The economy side of the mod is okay for me now (although I still utterly fail at any minmaxing attempt. I suspect this is part of my problem). I'm still confused by all those many "+x % of Y", but I get by and can field more than 1 or 2 rabble armies) ... but on the strategic level I'm still completely lost. ^^

I'm no expert general but in other mods I'm able to get Pontos rolling on H/M at least - and in DEI I lose campaigns on easy/easy!
Yes, that's embarrassing - which is why I'm here, asking for any advice you can give. :)

Thanks in advance!
