You're not alone, I think a lot has to do with the PVP being a hot mess right now. It's pretty bad, hit detection is spotty at best, and it creates scenarios where you look worse than you actually are.. Hell, I've basically had to give up on hand cannons because there is something wrong with them in the crucible, I've been point blank, crosshairs on someone's skull, pull the trigger... And NOTHING.. And they kill me...
