Very bursty comp. Still a lot of CC after clone nerf.
Shaman, Priest, Pala and Monk would all work with it. Shaman and Priest are better because their CC doesn't DR with scatter/trap/web. Priest better than Shaman because of feral symbiosis giving disperse.
Priest > Shaman >>> Pala/Monk.
Will be viable, maybe not top-top-top tier but easily 2.2k+ viable.
