To be fair, every snipers are a bit OP, they all have access to guns that can rip all the shield and a part of the health simply by hitting, and OS if in the head, but the downside being that it is not quite good at close and medium ranges.
The vanu snipers have a medium range too, less damages but higher fire rate.
I love playing both long range sniper and stealth hacker, both being really fun to do, but I can't bring myself to enjoy the other classes as much.
And I am not a good pilot, crashing most of my planes on the first landing try^^
But please, friendly fire is on, so stop shooting on everything that moves, it could be your own guys that you are killing...
And do join squads when you log-in, it makes the whole game more enjoyable.
