Good BRDs are highly desired in raid content, so you don't have to worry about that lol. Got a Dun Scaith run where we had 3 BLMs, 1 SMN and a BRD. Bard was able to increase the party DPS ridiculously high even if his own numbers took a cut. So all depends. They have some of the best utility and their numbers are nothing to sneeze at, but if you have the burning desire to be top DPS then I guess you could switch. I was actually thinking of switching to BRD once I get it leveled if I still like it at 60 lol.
