After reading about how experience works...

Makes me wonder, what is the most efficient lvl combination for my bard friend and me (rog) to be lvling together? he is lvl32 and I am 37 right now. He is going to close the gap some before we get a chance to play together again. I won't go way out of our way to get these ideal levels, just curious.

It is my understanding that total experience would make his lvl32 bard similar to my lvl37 rog?
