Toxic
This perk is just annoying to deal with, not only does the user not actually have to do anything, attempts to deal with them usually results in after-damage. This only gets worse as many zombies will just stay in a spawn area where survivors cant reach them. This is OP when paired with crit a cola or steak.
Zenlike
Possibly the worst of the survivor perks, zenlike encourages camping by giving crits and health making it impossible to kill the user. This would be fine if there was no healing or weaker healing.
Combustible
This just needs to have all bleeding weapons like the cleaver and boston basher, the latter of which can force an explosion.
Alpha
People just use this to grief by pulling you away from the person youre trying to kill
Ninja
People that use this never actually contribute, they just run around the map without fighting.
Thieving
This just breaks guns and you cant ever use it again.
