Throw out everything you know about rogue poisons. No, we need to go deeper than that. Throw out everything you know about rogues altogether. In the past few days, we've seen more blue posts on the official rogue forums than we'd seen since Cataclysm's launch. Poisons have been at the heart and soul of the rogue kit from day one. Even though parts of the poison system have changed over the years, the general concept has always remained the same.
Let me blow your mind: In Mists, you can have two poisons on each of your weapons at once. Let me do it again: All poison proc rates will be percentage-based. And a third time: Poisons are no longer applied to your individual weapons but to both weapons at once.
What does it even mean to put your poisons on both hands at once? What in the world am I supposed to write this column about if nobody's asking which hand to put Deadly Poison on any more? I'm going to slip and tell some new rogue that IP/DP is the best, and he's going to laugh and call me an old man.
