It a fair question, and its hard to say. I can understand the frustration of getting one or two shotted (very few escape the energy transfer that comes after assassin strike), but, by the same token there are alot of ways to counter what we do, and more then a few perception powers out there. I suppose when you balance what stalkers can do vs the sheer damage of blasters or the chain holds of controller, I would say we're on the tough end of the PVP stick, but, to say we're overpowered would be a bit much. Stalkers do require other AT's to adjust for us being out there, and sometimes its hard to avoid the AS once big fights start, but, I think with some thought most of us could put together a build that would be hell on Stalkers.
