hit 100 on my warrior last night (and 90 on the alt-account priest I was RAF leveling with), leaving me with my only non-100's being priest (91), hunter (90), DK (90), and demon hunter (n/a, haven't felt compelled to create one)
also have 90 RAF level grants with absolutely no characters to use them on.
still going with my druid for Legion, though. it's hard giving up the ability to fill any role, my only real concern is the amount of effort it may take to keep 3-4 artifacts powered up enough to at least run 5 mans competently.
