So was recently thinking of starting up a Rogue. I've never gotten one above ~40 before but thought I'd give it a go in time for the expansion.
The one thing that turned me off the class is it's apparent reliance on Cool Downs. Keep in mind, I'm not sure about the validity of this, that's why I'm asking in the first place. But from what I can see, without any cool downs active, you're next-to-screwed as a rogue. Vanish, CoS and Blind are a few examples (excluding ones like Combat Readiness, Dismantle, etc) that look essential to being viable in a fight in, as an example, a BG.
And even if you do have them all up, you're going to end up blowing them all to kill that pesky Hunter, only to have nothing left up your sleeve to best the [insert class] who's coming up the hill. I'm not implying that taking on two consecutive enemies at once should be a piece of cake for a rogue, but at least I'd have a chance. On my lock or shaman, I rarely actually have to use a cool down. Things like death coil I'd only need in a 2v1 situation, unlike CoS for example which is necessary ALL the time.
Like I said though, I might be completely wrong about this. What I"m looking for is someone to confirm it. Are rogues really that cool down dependent. Do you view having cool downs up during PvP essential or just a bonus?
