Hehe, I started that game taking outposts from afar, but once I unlocked some of the later Takedowns, it was melee all the way.

As for snipers in PvP, they're not that overpowered. A good sniper is overpowered, as is a good shotgunner, or a good SMGer. Most people get taken out by average snipers because of their own careless maneouvring, I find.
