Fragger Nades - Fine, absolutely fine, 1 nade for 15 seconds, which means you have to be good with them to be effective.
Nader Nades - A bit spammy to some people but considering her role I think it’s fine.
Fletcher Stickies - this is the merc I do have a problem with, the amount of times I get killed purely by stickies is absurd, and it’s worse in comp. A cooldown nerf would be nice, and maybe a max of two, but idk, the second nerf might be a bit much. I just feel like he’s too spammy as is.
Proxy - same sort of deal honestly, there’s no punishment to proxy for her nades being blown up by enemies and there’s no other way to deal with them. It’d be nice if mines were triggered based on speed, so you can crouch walk past them or disarm them. But that’s as far as I’d go for nerfing them.
Molotov - it REALLY needs an arm time, way too often I come across Stoker’s who panic throw their molotov and it gets really frustrating since there’s no way to get away from it. A 0.5 second arm time is all it’d need, just a half second to back away a bit so you aren’t killed by some rookie Stoker who saves them for moments like that.
Thunder - Really needs a buff, I say scrap the flash bang aspects but work on the concussion effect, the messed up vision etc. Have it disorient people more and more the closer they are to the nade. Maybe even have the first person models actually put their hands in front of their face like the world models do.
