First time I may have something to contribute, see if it works
All warriors, know that you cant use Deadly Calm + Inner Rage at the same time.
I however found out, that when you use Deadly Calm at 75 rage and you use Inner rage right after. You have both buffs.
This shouldn't be intended...but I cant come up if the buff actually works!
For all people who dont know.
Deadly Calm: You dont lose rage, but you still gain rage.
Inner Rage: 15% more damage, but all abillities cost 50% more rage.
I checked, and searched 3 times. (I could have overlooked it) But I didn't find any post about it.
