its always bothered me how snipers/slingers, or any ranged class for that matter, auto-turn when you get behind them. I play a sniper and benefit from this but it really does take an important skill aspect out of playing a ranged class to have them do this. I played rogue in wow would position myself behind many a caster and move with them as they would try to turn and face me. In this game ranged classes auto turn. It's kinda ez mode. Like I said I benefit from this as well on my sniper it just seems kinda silly that I can take a sip of my soda with my mouse hand while I have a melee on me regardless of their position.
Cover and snipers would be pretty damn useless if they had to leave and re-enter cover just because a melee got behind them.
