I figure id share with you the way im quad-boxing my 4 shamans. I call it the slingshot method lol. All 4 of my accounts have some kind of 60+ character on it. So what i do is i quad box with 3 shamans(sitting one out) and one 60+. I just constantly grind instances and it is very good exp. After a run is over whoever has the most exp, sits out and i replace that one with a 60+ they all stay very close in level and instead of asking people to run me through instances i can do it myself
