I believe that it really should be stated that this whole argument is kind of silly however Bards and mach damage is not lower then other classes due as much to there utility as stated before you already have built in mechanics to deal with this. Bard damage is reduced due to the fact of how much mobility they have they are the MOST mobile job in the game this makes dealing with mechanics while still doing optimal DPS considerably easier for them. If you think that a class can have that much mobility and still do damage on par with every other class then you would be sadly mistaken. Also do not try to state that WM is a reason to give them more damage as its not even being used as intended right now. As rotation wise you literally just turn it on to activate a few abilities then turn it off.
