Flying fists + Round 2 are amazing, I re-proc UH while still on my cooldown for Blaster Whip constantly. Things die quickly when you are constantly hitting them with some of your strongest attacks.
Survivor's scars isn't worth three points, if you're having to get healed by the healer AT ALL in group play, you're not doing a great job managing your hate. Plus, the bonus healing is minute. If you're getting healed for 2k, it adds 200 points on? That's never saved anyone's life, who is actually in danger of dying.
