How about we use the next expansion at making the older classes feel fresh again.
JUST A THOUGHT all you people wanting new classes, if we kept that up we would be seeing less and less of the older classes. I would love to see some fresh new love much like the locks got for mages, pally, shaman, and rogues and basically all the older classes.
But you know lets keep throwing more things into the game so even more things become unbalanced and more annoying =)
