I'm surprised Metamorphosis is so strong, but it looks like the clear answer against melee. I was hoping to be able to get Siphon Life as I assume I'd just be putting corruption on everything I see while I run away from whatever is attacking me. However, I see the theorycraft behind 600% additional armor when melee is beating on you. I guess I have 80 levels to figure out which spec, but I'm glad to see the positive reaction towards locks from those who play them.

How many locks can you get away with and still drop folks fast? For example, 4 boomkins is a serious disadvantage compared to 5 due to their lack of burst. 4 shamans isn't really that big of a change from 5 so you don't feel it much. What's the story with locks? Could I get away with 4 locks and be ok? How about 3? I think I'd prefer having at least one resto druid in the group, and possibly two.

Side question: does siphon life work on seed of corruption, or only corruption?
