ok so heres why anyone considering a sniper should stay away from snipers for pvp. I'll help you visualize it:
you (pewpew) -----> headshot on dumb person = you win
you (pewpew) -----> |PILLAR| smart person = you lose
basically, anyone can los you all day if they want and are smart enough. go merc, they have heavy armor heals and just as much burst. *hugs all around*
edit: this seriously isn't a troll post, ask any other sniper that isn't bad
