I feel like it would be cool if the dev made it so using Butcher Block wasn't just a dps loss for more emnity, but made it so it fit into the warrior kit in some way.
I think making it so the last hit in the combo made your next fel cleave/inner beast do x% more damage would be a cool stop gap. SO that you always wanted to weave in 1 butchers block combo into between Cleaves when not running inner beast.
Then combine unchained and defiance stance into just a cool down with increased healing and health. As the current warrior play style honestly makes a lot of sense for the class, despite it possibly not being thier intention (?).
As shirk makes the whole stance thing kind of irrelevant any ways as off tanking is as easy as throwing you aggro at the MT.
