Blood Craze is completely useless. At 30k health that's 1800 health over 6 seconds, or 300 health per tic. You'd be better served with a pocket Druid, Priest, or Shaman. Paladin would work too, I guess, but it's easier to stop them from healing.

Going with Cata figures, where PvP gear has Stam out the azz, 6% of even 100k is still only 6k health over 6 seconds, it doesn't stack with itself (Meaning if you get crit 2x you don't get 12% life back, it just refreshes the duration) and the measly amount of health returned is laughable when compared to the amount you just took.

Second Wind is EXACTLY the same strength of heal (1% life per second) which is still pretty useless, what makes it GREAT though is it's 2 talent points instead of 3 AND it gives you RAGE with witch to murder that bastard that just stunned you.

What would cause concern for you as a feral Druid in Bear form would be if these were INSTANT heals (making them actually not too horrible for the talent investment) but you'd still be better off with a healer in your back pocket. Warriors were designed with the worst vulnerability and best synergy with healers, to the point that if the warrior has a healer, he won't die, but he drops faster than a mage to a Boss's Cleave without one.
