About the weapons problem:
Peacekeeper
I feel that it needs to be a "finesse" shotgun, high risk high reward. If i would tweak it i would keep the damage but reduce the magazine size to 2 shoots or a very shy maybe to 3. As it's right now there's enough shots so you can just jump in and miss 2/3 and still down someone.
Evo
I don't feel like this weapon is overpowered, not with the peacekeeper in the game. Also the game needs a noobtube, what's now the peacekeeper, to give a chance to less skilled players. I would keep it as it's. I don't even feel like it's a good weapon in my sincere opinion. But again it may be because of the Peacekeeper and because i play on PC.
Wingman
While this weapon is only good in the hands of very few players. When it's good it's GOOD. It's in a strange spot where it has enough alpha damage to 2 shoot anything below purple armour (2 HS for 90 damage = 180 damage)
It doesn't suffer from range problems like the peacekeeper and can be used without having to charge it.
Also let's not forget about the magazine size that goes up to 12. Meaning the potential to kill 6 non purple players, 4 purple or 2 if you don't go for headshots.
Also lets not forget it's a pistol, i might be wrong here but that means a faster ads move speed.(At least that's what feel like when in comparison with the spitfire)
So i dunno, i know the wingman is a finesse weapon that rewards accuracy but i feel that when you have such accuracy it make everything else, with the exception being maybe the peacekeeper, completely irrelevant. And that smells like a problem in itself.
If i it was me i would reduce the damage to 30 in body shoots and maybe increase the damage multiplier of HS to 70. But oh boy.... if respawn does that i can already hear the screams of some players.
But again that's just me.
