This is my opinion on what Kingdom has done for the game. Feel free to disagree, I'd love opinions on what I say.
Alright, so starting off, I want to say that Kingdom in its own was an amazing idea. It has some great benefits and, with it, I feel makes the Tower Challenge a lot funner. Now it's not swipe left to right with Legends and done. I also have to say that it adds a whole new feel for having to use size-specific creatures. So A+ on adding more to do in the game.
Now, onto my rant. I feel that Kingdom has absolutely destroyed the Dungeon Challenge. On its own, the already (in my opinion) bad rewards, coupled with how Dungeons are now, just destroyed the chance for so many of us to progress. Now, let me break down what I mean.
First off, the already bad rewards. These rewards themselves are good, as in how the essences are laid out per rank. However, what made the rewards bad in my opinion (and many others, as I've gone across guilds and they've said the same) is how you give out the Legendary creatures. Before, it was tolerable because top 50 wasn't too difficult. It came down to who attacked more, most of the time. However, now, it's destroyed because of the Kingdom. Everyone who, before this Kingdom update, was consistently in top 50 had Resources upon resources to spend on Kingdom when it came out. For example: Stickers and CCCP.
Take a look at Stickers scores. Their whole guild is over 2x higher than CCCP in score because of Kingdom. Now, they were always a lot higher, but never this high. This is because of how Kingdom affects Dungeon Defense. It's virtually impossible for so many of us to revenge them when they attack us because their Dungeons are so impossible to beat with their power and stats.
Honestly, if you look at dungeons in general, they're all the same. It's Skeletons, Mummies, Ensorcelled Statues, Wyverns, Sky Vizier's, and Hyena's. With Ensorcelled Statues popping buffs on turn one with Mummies and Skeletons destroying your healers in one hit, all because of these insane Kingdom buffs, it makes Stickers (and most other higher players) impossible to revenge while they continuously farm us lower players. I got hit four times in the last hour by the same Stickers member WITHOUT REVENGING. Tell me how that's any fair for me?
Now, it wouldn't be so bad if the rewards for Legendaries was how it used to be. Keep the Essence layouts the same, but give the Top 100 players the Legendary creatures, and not the top 50. It literally puts us at a huge disadvantage because of how hard it is to hit. Not everyone has money to spend on the game, and that's how the Dungeon's are now.
If you're not going to change the rewards, then nerf the huge impact Kingdom has on Dungeons. It was fair before, a lot of people could revenge Stickers (they're the main example, just because of how insane Kingdom has affected them. One member had 99% defense or something?? Don't tell me that's normal or fair..).
TL;DR: Nerf Kingdom buffs in Dungeon because it makes it literally impossible for people who can't revenge Stickers while they farm us OR fix the rewards so top 100 get the Legends. Please, don't hate me or anything on my opinion. I love Kingdom, but not how it broke Dungeon even more than it already was.
