The only change Warrior needs is the animation for decimate.For such a mighty move it lacks the animation to create that impact.Should make it create a huge explosion.Possibly maybe even make the entire screen shake too and give a 2 second stun to all enemies on map.
Also for stance dancing the cooldown on our stances is a bit too long.I think it needs to be shortened for better stance swapping.
And seeming as tanks don't really need tank LB maybe change warrior lb to super fell cleave.Which is single target damage lb which can work with bloodbath to restore warrior to full hp.
