I don't think there's a huge amount of bloat right now but probably are some places they could adjust things without affecting rotations too much. I do feel they would need to be careful, though. For instance, Brutal Shell spam has saved my butt more times than I can count. So it would be detrimental in that case to make that combo a single button that cycled through the actions. As someone mentioned, abilities where only one other possible button could be pressed after it? Possibly, but only if it wouldn't mess up weaving or things of that nature.
