I agree with a lot of stuff in this post but I find some of these very questionable.
Hot rod chomper: has 125 health to trade off with speed. I think the problem is the insane reduction of aiming sensitivity because of the goop.
Chomp thing: needs a small spray damage buff and possibly a health buff but vampire effect should stay unique to vampire chomper.
Metal Petal: she is a long range character with her own heal pot combined with a lot of health balanced with lower damage, i think she's pretty balanced.
Frozen citron: his freeze rate is nowhere near fine and his damage is pretty high for a ice character.
Fire rose: 50 (full charge) splash damage with fire damage underpowered?
BBQ Corn: I agree on a nerf on him but it should definetly be for projectile speed because it is insanely fast, almost a hitscan. Take for example lil drake, he is one of the more balanced fire characters.
Painter and centurion: no buffs required really, although i wouldn't mind a buff for painter cuz his my fav.
Moto-X star: I think this character is fine the way it is because it's kind of an counter to citrons, chompers and peashooters that have mobility abilities and it also has splash damage.
I don't agree with z-mech health buffs because it would be smarter to nerf turret modes and chomper's goop against mechs.
Here are my suggested changes and i am interested what you people think about them:
Nerf all turret mode damage resistance buffs and turret damage back to what they were in gw1 because at the moment you can just go root in front of enemies and mow them down. The description of pea gatling suggested a long range use for it but the changes to it in gw2 suggest otherwise. People didn't really use them effectively and sat there rooted for a long time and eventually got ZPG'd and pop cap seemed to assume that it was underpowered which most definetly wasn't the case.
Electro citron: Significant long range damage falloff for charge shots and splash damage nerfs ( maybe 2nd from 30 to 15 and 3rd from 45 to 25 or 30 and with the plasma pea 3rd charge splash damage delay) because they are too damn high and you also have to keep in mind that it is an electric character
Citron ball: make it take critical hits because a good citron is hard to hit and it would encourage citron players to play more attack mode
Rose: fix hitbox so it is easier to hit because it is harder to hit than imps which really doesn't add up because imps have less health
Husk hop : nerf damage per shot from whatever insane amount it is atm to somewhere around 3 or something because it can destroy a fresh full health mech even with it's damage resistance which is the dumbest thing i have ever witnessed in the entire game. I have also been killed by it by accident dozens of times when corns try to get on the roof where i am.
Parrot pal: egg strike would make more sense if it was like the cone strike from gw 1 or the corn strike but that is very subjective.
Goop: slows zombies down more than super sticky goop charges quicker and does more damage. Fix would be to make it slow zombies down less than ssg.
