I've had bad warriors question the use of Thrill of Battle. This one is totally a no brainer. It will heal you and raise your MAX HP. Say you got 10,000 HP, thrill of battle will heal and raise your HP by 2,500. That's 2,500 HP of throw-away HP, so it's X(after damage reductions) - 2,500. A large portion of attacks end up more away from nothing than your actual HP.
