The only change I would make to Rage of Halone is I would change the enmity to be applied at the beginning of the animation rather than waiting until the damage occurs. The animation time can be a nuisance if you're using it to pick up a freshly spawned add or follow up a provoke. Otherwise I might move some of the threat from RoH to Fast Blade so the overall combo is a little smoother. But for the most part it's fine and these complaints are just inconveniences.
