1. Defiance no longer reduces damage done and has a permanent 15% increase to healing received from curing magic instead of being based off wrath stacks.
2. Maim no longer increases our damage by 20% instead debuffs enemy target lowering their physical damage done by 10%. (With Defiance not reducing damage done we don't need a damage buff ability)
3. Storm's Path now heals for 100% of damage done up from 50%.
4. Bloodshower makes Bloodbath a permanent ability instead of extending it to a 30 sec duration.
5. Steel Cyclone heals for 200% of damage done.
6. Unchained increases all warrior self heals by 100% for its duration.

The changes to the Wrath abilities would let the Warrior use all the abilities for self healing depending on the situation. Inner Beast for single target quick heal, Steel Cyclone when tanking groups of adds and Unchained when a quick pick up isn't needed but you want to help the healers out some.
