Well half a lvl is normal, but if you do DM 4 times in 1 hr its 2 whole levels, thats 4 lvl's every 3 min (countign all caracters).

You just need to practis the pulls and specc full frost! put your alts in a saif spot run threw half the instance and bring all the mobs back to your toons and BOOM!

remember Sehld upp + icelance!

also you only need to kill the mobs aroudn 150 feet away from your toons to get exp so dont get to close and then have them killed off by AoE.



(btw just to make you feel bad lvl 49 to 50 in ZF takes 4 to 5 runns :P)
