Gun scum needed adjusting, but the class fantasy of being able to be the “pure shooting class” was actually novel and fun. It was a nice change of pace for me, and I think a lot of others. While some players insist that they do not want others to be able to play what they want, they don’t have to play it.
But since you can only get ammo back in melee, the class is extremely clunky to play; building your gun scum leads to the class being extremely poor in melee, and your team mates who are melee specialists WILL exterminate every viable target, often while you’re trying to slap it to death. It’s incredibly annoying how much time I’m spending trying to hunt down and kill a SINGLE Elite/Special before the team kills it - and even then to only get back enough ammo to shoot for a few seconds.
At the same time, Rampage and Chem scum can still abuse the talent to be able to put extremely high DPS on every single target in the game, regardless of armor type, with Needle Gun.
I suggest that Pickpocket be moved to a sub-node of Desperado, so that getting it requires one to be specced into ranged combat. I would further recommend that it be altered so that the enemy must be killed at close range (not simply melee), forcing the player to be nearer to enemies. Finally, instead of instantly refilling the pockets, cause the enemies to drop a pickup that only the Scum can see that must be collected by walking over (that will still only refill ammo to 20% of max).
In this way, the Gun Scum must still play close to enemies to maintain ammo, putting them more in danger. It also means that heavy enemies can pressure them away from ammo drops, properly walling the class off.
On top of this, I would recommend some nerfs;
The +50% dodge distance node is insanely strong. And I mean insane; I never, never feel danger in melee even if I have no ammo, because the dodges are so absurdly good. Gun Scum should not be that safe. They should have to play around the edges of enemies and have good positioning.
Second, revert the ammo increase on Boom Bringer. It’s a very strong tool, but with four charges it is too strong.
If Gun Scum is still too strong after these changes, then there are options to cause the Pickpocket node to give some downsides, such as decreasing damage or cleave. In this way, players can choose to play an “honest” Gun Scum with full damage, or one using inferior ammo they pick up along the way, giving them infinite ammo but reduced DPS at any given moment.
