I think, even though I am still not particularly fond of the clipping issue caused by certain quivers, that I am just going to go ahead and stick with the Bard, as I know the Bard better than any of the other DPS classes and would have an easier time with the rotation / priority system of the bard than anything else at this point.

If when I decide to try something else, it will probably be either a healer (Scholar), or Machinist at this point.

Thank you all for the help deciding these things. I really did need to hear the opinions of several people about what I could come to expect with Summoner and Black Mage before I could truly make up my mind on what to play.
