Thats good to know, so now I have to decide whether to switch to a prot pally main at level 24 or keep the shaman... is the pally significantly better for instancing (I want to do a lot of instances from WC all the way up to heroics) and is it significantly worse for pvp? If 5 shamans is way better for pvp ill keep the 5 shamans as BGs/arena will be my primary goal I think.

Also any hints on granting levels? it doesn't seem to work, although I just realized my 4 clones were still trial accounts until early this morning when the restrictions got lifted - maybe thats why the grant level option was greyed out.
