This enemy will make my blood boil!

As I reached Lv. 30 and entered Stranglethorn Valley, an old fear started to rise in me. Bald headed dudes in green robes, healing themselves to full health so I have to basically kill them twice... As a warlock, I have to drink after every mob, dragging the jungle medicine quest like hell.

Of course, I'm talking about Kurzens Medicine Man, my most hated character in the game.

Do you feel the same about those things or do you have another mob that's even more annoying?
