oh, and i took the liberty of checking your blood spec. i don't really know what kind of spec it is. it is not DPS, because that is the 51/0/20 spec. it is not a PvP spec, because you got a taunt glyph. gear and glyphs seem to form a tank spec, but you missed toughness in frost. i assume it is a tank spec. that incites me for the following hints:
use the 53/8/10 spec.
