I'll miss it too, but not as badly as I first thought. The new changes to Prot play sorta like Gladiator in a way. Yes, they can't queue as 'dps' in a raid with it, but I barely feel it's left pvp wise.

Actually, been seeing locks with over 1 million health bubble and doing absolutely nothing(standing still). Had to armory the guys who were doing it, they mostly have every lifesteal/healing talent, but nothing lines up even doing my 'napkin' math of their abilities. Soul Leech 'bubbles' of that magnitude that aren't bursting down when half a dozen people are focusing him would take something like a million dps to not only get, but keep 'growing'. Seems more like something is broke in the scaling on Soul Leech.
