I think that they are the best at everything in the game. They are best at CC. best ranged, immune to CC many utilities and the broken stealth uptime. It is not really something I could get used to so far. We can only hope for balance and at least they are working on it.
I think the Rogue was ok the way it was at launch. Nerfs came only because people complained about it dishing out the highest dps in the game. But if you think about it, Rogues are only good at what they do, namely, DPS, so why cut back and nerf a specialized class like that? This class is meant for quick, action-oriented combat. It has no high armor, like the GWF, who can work well as an off-tank, nor do they have any other abilities to enhance groups. They just deal damage.
