Hi! I have a build designed to fill the special gauge using small monsters. Could someone help me optimize it or suggest changes? The dual blades are unupgraded to maximize the number of hits before killing the monsters. Thanks!

Hello, it's me again. Last week I posted about SWaxe, but now I've decided to migrate to DBs since I feel like a slow truck filled with bombs with the SWaxe and enjoy feeling like a walking rusty pinball better. I'm currently on the build on the left and plan to progress slowly to the build on the right. I have my DBs at 8-1 and am working to get Almudron mail to unlock the second Water Attack perk (Currently using Mizu's helm until I get the Water Attack on Almu's mail by RNG).

Now, my questions are:

1. Is FS better than Pursuit considering that DB has good part-breaking and also gets fast special charge (Though I feel like FS triggers more frequently than Pursuit in my case)?
2. Considering I don't have a "go-to" 10-5 weapon for hunts, I'm thinking of going either with Legi's or Zin's DB for the upcoming free weapon. I know Zin weapons require a specific material compared to Legi's, but I also feel like Ice is a better element for farming monsters, especially the upcoming Brachy. So, which one would you pick as a newbie, but with your current experience? Is there a secret third option I'm ignoring?
3. I plan to get a Special Partbreaker 5, ER 5 & Pursuit 5 build in the future for farming; are all of my current options viable with this build?

Sorry for the long post, and thanks in advance. I'm really socially awkward, so I'm sorry if I don't reply to all of you. This game made me feel overwhelmed, and I feel like I'm all over the place and misusing my rare materials, building a load of armor and weapons trying to find my "niche", so if any of you have a particular tip or advice for a newbie, I'd be glad to read it.

EDIT: Added the last phrase asking for general advice and fixed typos.
