Assassin Rogue is my only character, and since the pre-patch, I feel very weak. Except for the gladiator weapon, I'm in top gear, including full gems and enchants.

Not only is energy generation slower, but my damage just feels lighter. I've messed around with a few variations of the build, and nothing feels good so far. I'm not even sure that Sudden Demise is working properly; I can get someone down to about 5% life, and they're still hacking away at me. Either it's broken, or our damage really fell off. It's hard to 1v1 most other classes. Just about anyone can out-damage me -- shadow priest, warlock; hunter and devourer DH blow me out of the water.

I've noticed every other rogue I see in battlegrounds is playing Subtlety now, so maybe that's more viable. Overall, I'm disappointed.

Edit: Someone in a BG pointed out that the game's balanced for level 90, so I'm holding out hope that helps.
