Healing/Mitigation wise WAR already has a great concept that just needs to be improved upon. Self-overhealing mitigation is the way to go I think.

Allow ALL self imposed healing (except potions) to create a pool of additional HP in the form of a buff. All incoming damage passes through this first before making the pass through SS and Adloq. Do not allow SS/Adloq to take this additional health into consideration when being applied.

Something like Red Mist would be an appropriate title. This can be an additional benefit of Defiance.

Other abilities should stay/change as follows.

Bloodbath - it is fine as it is. Yes it may not look like a lot at first, but 25% over 30s does add up, and for AoE tanking is actually viable (especially coupled with vengeance).

Storm's Path - Maybe change this to 100%, considering the fact you are using this skill instead of increasing enmity or increasing damage output - I feel that 100% isn't overpowered.
