I don’t pvp so obviously no expert but I can see it being very annoying in a team setting with it causing stun DR for when you actually need a stun for clutch moment or something.
You actually can hold 70% slow while still dosing.
Concussive shot Into steady, rapid fire, steady, explosive shot, steady, arcane and stun kicks in at that point, allowing to double tap aimed shot or something similar.
Problem is how unfeasible it is in more than 1v1 scenario.
