Understandable. However I think the stun is more of a reward for landing it. Yes it basically means you're dead, but that's the consequence of getting stunned. I do think it's a bit unfair.
Maybe we could have a damage reduction added to players that are stunned? Like a 10-25% damage reduction while stunned. That would make it a bit more fair for those that abuse the stun with a weapon that can basically "one shot" you while you're stunned (rifle/pistols/revs). I like to play a bit more fair lately and instead of using a gun that will guarantee me a kill if I stun someone I'll use snipers or shotguns. I'll admit it does get a bit boring to just spray your enemy down with a rifle/pistols when you stun them. Got to give them a chance
