I just want to point out that "support" is a very general word. You can be "support heal", "support debuff", "suppert sleep", "support offense", "support defense". So SMN excelling in one of these, wouldn't hurt any of those excelling in the others. (Most likely we would be best at defensive wards, while BRD and COR will be better at offensive songs/rolls). Of course in this situation it just because a question if we are stealing SCH buff role, or if they took ours to begin with.
