On my sniper, if you're melee, well odds are against you closing in. And most of the time, when you finally do close, I can knock you back or just finish you off, its the same on my gunslinger. The best counter to a sniper/gunslinger Ive seen, is having a healer to keep you alive long enough to do your damage. Im not going to blow my own horn, but 1v1, I can usually come out on top against most players. My advice, tag team and expect one of you to end up on your back.
