Well, since the main story brought me to Ul´dah at level 16 I figured I might as well get started on the PUG part of the bard. With the 50% exp bonus you get when leveling another class it took me a little over an hour to get to level 11. So I guess it will be maybe another hour or two before I reach level 15. Of course I have no idea if it was the right/most efficient thing to do. Maybe it would have been better to wait until I was at least lvl 20 in ARC before switching. But I was in Ul´dah. The PUG guild was in Ul´dah. It was like fate brought us together...
