Vassili&Redeye: Bad/Asshole/Douchebag players often play them or people trying to be “cool” (plus way too many players on 1 team playing them) Also badly thrown smoke nade can destroy a push and it also annoys me that Vaseline can have a machine pistol as secondary (come on, he’s supposed to be the weakest in CQB and yesterday I saw a Vassili on my team kill 2 Auras at close range with it)
Aura: I hate her the most due to the Jesus Station- it has the same healing rate as Sawbonez’s bag but heals constantly. I know you could use explosives/shoot the HS but sometimes I play weak (Sparks) mercs without explosives or good guns. I’d love to see a system similar to how the medbag in Battlefield 4 works (as long as you’re getting shot/suppressed the medbag won’t heal you and after that there’s a few seconds low cooldown) but slightly different: as long as either you or HS is getting shot it won’t heal you (and 1-2s "cooldown period) @MissMurder PRETTY PLEAAAAAAAAASEEEEEE
Rhino: Boring, TF2 Heavy without Sandvich 
Arty: Artillery Strike needs a few tweaks (locking while moving for example)
Nader: Martyrdom (should take a few seconds to deploy like Phoenix Self Revive)
Phantom: Annoying to play as due to overnerfing
