I don't really see ARC becoming BRD due its mechanics...like allowing BRD to "nock" music notes would be at least bizarre lol. But actually none of the current classes actually fit BRD standards...but who knows... i do am curious to see who will become BRD and how they will deal with actions...because it would need to block even the native actions from classes to have BRD as support role...or just put so many actions at BRD exclusive set that would leave no space for DD actions.
