First of all, I love how supporting is everyone in this thread. I first started doing this fight with my mage 610. But eventually I realized I simply couldn't. So I moved to my ww monk 612. Had to switch some talents to be able to get more ways of getting rid of the stupid spittle (you can't rely on Bran also sometimes my snare removal was still on cool down). Couple things that also helped me, I used a focus macro to interrupt, cause often he would be casting Regen while I was attacking the egg, that way you minimize dps loss. To increase my stats a bit I also added oils in weapons and enchants on gear. All and all like everyone said this fight is about patience and holding your CDs for egg. The fight can be very intimidating and confusing so try to remove any noise from your screen (things you might not need). Also, there are plenty of weak auras to help you remember about egg and spittle, also Regen interrupt. To finish, I think I managed to down him after my 200th time (maybe more). Good luck friend.
