There are some hit box detection issues that get exaggerated for some reason if you put a scope mod on. They are still there without one but manageable. Biggest problem is draw distance and map design. The sniper spots are so obvious on the TDM maps that going to them is just asking to get cloak shotgunned in the back. So like a few have said you have to get good at the quick medium range shots. Camping the hallways on observatory is good for this.
But I don't know what they are talking about quick scoping as it doesn't exist in defiance, at least in the COD, Halo, BF, etc. Sense. Half the time my hip fire reticle doesn't line up with my scope cross hairs, assuming this is some sort of TPS thing that throws it off depending on how I'm moving which may give a weird angle, so it does require a quick adjustment.
