I'm confused with some of your macros. Overpower doesn't heal you, so I don't know why you would want it macroed with convalesence. Also, Convalesence and the Fury stacks don't increase healing you receive from self heals such as bloodbath, Storm's Eye, Inner Beast, and (I think) Thrill of Battle, or Second Wind. So Convalesence doesn't really help maximize any of your self heals.
Yeah sorry.. i'll need to adjust it... that second macro is to be used in Conjunction with BLOODBATH. The internal release makes it crit for additional heals. It's really only intended for tanking a group of 3 to 4 mobs where that don't hit hard and don't require crowd control.

I'll fix the macro now.
