As I say when writing essays, everything should have a purpose.
I think by introducing a 2900 cred gun, riot SHOULDVE made an attempt to counter the light shield meta. People rarely buy heavy armor these days, because in pro play, "leg shots" don't really exist - it's all headshots and bodyshots, and for teams with vandals, heavy = light = regen armor (for phantoms, there can be arguments for heavy armor, but if u get hs, they prob be hitting a bodyshot on u easily too)
with 50/bullet and 200/hs from any range, this gun does NOT care whether you are runing heavy shield or light shield, and in fact, all possible combos with warden and phantom/vandal bullets (50, 35/39, 40) actually do NOT care about light or heavy armor (if you take 1 shot, it's 100 health - 40x2 < 100 < 35x3; if you take 2 shots, it's 50 health -> 40x1 < 50 < 35x2)
riot should've made this gun do 44 damage imo. I know this number LOOKS weird (45 prob better, but phantom does 39 so who knows), but it means 125 < 44x3 < 150, and 44+35x3 = 149<150.
This gun just reinforces the light shield meta, and I don't really see a purpose to it.
