A good sorc that knows how to focus down guys that the mdps are having locked down instead of alttabbing dots will STILL top damage over anything besides a decent 2.6 smasher, and be an absolute pain to kill. In regs.
From all the classes I have on 55pvo, my balance sage is the most efficient energy invested / number of top reg dps spots, by a long shot. That char isnt even geared, and Im pretty mediocre compared to the real top balance/madness players on our server. When im playing carnage i have to be in shape, drank coffee, habe no lag, and be warmef up to keep up with some of my buddies who are really great at mara. Earlier today I had a game where all those conitions were met, and i managed to stay within 5% of someone I consider to have mastered the spec. Next game I had big lagspikes and i didnt hit half his damage, lol. On my sage I can just q stoned and hammered and sleep my way to top 3 dps (and i don't tabdot).
So yeah, maybe not better, but alot easier for sure.
