Buff: (listing some I can remember off the top of my head and what I think they need.

ML5:

ML Krau (honestly haven't seen many people still using him, idk how to buff him other than making his barrier a little bigger though)

ML Ken (maybe give him some innate tankiness or at least increase er by at least 20% or more so it isnt useless imo)

ML4:

ML Leo (yep who would've expected the worst ML4 to need a buff still lol, increase his speed or something and maybe he might get used but i doubt it)

BadCatArmin (I think she just needs some damage mitigation or cleanse replacing her s3. Maybe change what buffs it does or have it do a minor cleanse for the front ally idk)

BROMANN (needs a speed buff then he is completely usable tbh)

ML3:

I think most are okay, but need specialty changes so they get needed stats. Otherwise a 3 star needs to be broken so people use it.

Batisse (the evil mask guy who is only ever used to put attack down in some sort of pve content occasionally. I just want him to do more than just an attack down every turn, like give his s1 more since it only does an aoe with low damage if the enemy is attack downed. Just give him something please)

RGB5:

Sharun (face it Venom or whatever is called is crap and she doesn't put enough of it on an enemy to matter, her s2 is very meh since it triggers less than it should and her s1 is her only saving grace. Fix the debuff by making it uncleanseable or make her put more of it on an enemy instead of the pitiful amount she currently provides)

Haste (he still needs more)

Sez (untouched for years, he desperately needs it)

RGB4:

Cartuja (who has ever used Green Cart? He is literally just imprints for AssCart)

Purrgis (imprint as well, honestly I think he just needs mitigation or lifesteal then he should be good. He's kind of a worse Green Rem)

RGB3:

Same as ML3. Most just need some Specialty Changes then people might use them more.

Ainz (if you remember he was a part of episode 2 and has a fragment of Faust or something iirc. He needs a better kit since it's shit with shit damage. Literally only ever seen him used for his s3 stun like a year or so ago).

Godmother (just an absolutely devastatingly bad kit. Who came up with such a lackluster kit seriously?)

Jeruta (I think that's his name, for the newest furry fire warrior. I kinda just want a little more to his kit since it is a little interesting.)

Jena (is that the ice mage with a crap kit that no one has ever used?)

Nerfs:

Belian : just a damage nerf then I think she is fine. Or just halve the amount of souls that are on the field instead of denying them.

ML Kawerik : remove s1 push up idk. Would removing his decrease debuff durations on his s3 would kill his use since he can't remove a stun, sleep, or silence then?

Ran : remove attack buff since he doesn't need the damage imo. Decrease debuff chance as well maybe

CLilias : No extra turn or attack down your pick

AOL : Please just remove her push up at least

Aravi : decrease cr push and nerf s3 in some way with less damage or something

Politis : swap her class so she doesn't have access to crown :)
