Some time ago I was questioning effectiveness of all sniper builds, but there have been done some critical table adjustments so for now to me it seems that snipers are quite balanced. I bring all kind of builds to TC like snipers, bursters, lasers, rockets and every build can be useful in certain situations.
Maybe that's why they are called snipers? Haha oh wow, what a thought process.
You should always have some means how to counter that. Sniper can always retreat, when he spots someone that might be stronger and he wont stand a chance against him. However, big gunner hasnt got that luxury, so he has to survive some initial shots. With boosted sniper damage, that wont be an option.
I use only SG snipers whenever I'm playing pvp and I think they are quite ok. If you don't know how to play sniper char, then play pac man or something.
So if the game is ever going to turn towards "having just one character" snipers will need a buff. But that buff has to happen in gear, not crit tables or perks. If you buff sniper perks, low gear trolls benefit most.
