I am more or less sure I didn't understand you right but reassure me. You're not asking them to make my Blood and Thunder useless before I play with it, are you? And if you are why do you hate your brothers and sisters who decided to follow the path of the masochistic meat shield?
EDIT - Just so my post is on subject I don't think it's implemented yet like others have said but with the cap raised to 85 on beta we should know soon if it made the cut or not. Also didn't Blizzard say it was mostly for PvP on enemies that kite or eventually encounters like Grobbulus or phase change on Putricide if it has a long enough uptime to stay on while he's leveling his Alchemy? Probably other examples but I hope you all get what I'm trying to say. (I'm not 100% sure how clear I am sometimes)
