set your clones up with a hor key to make them stop (ie back key or a spread macro etc, something to break follow.) Engeneering helps alot as a pally tank cause you can make crappy little dynamite sticks to pull at range.

Set your shaman up at a spot that is not in lign of sight. but facing where your pally will be. The 5 pack is actualy a 2 pull and a 3 pull. pull which ever is closer. If your going to the right first, pull the 3 pack by barely hitting the first guy with the edge of the dynamite circle. then LOS the lock so he comes to you. Now get around the corner, judge one mob then get a few swings on the other,and then ,kill the pet. It will die fast. Then finish off the rest. If your getting owned too fast then buy some gear from the AH beacuse at low levels adding 50 armor to your pally is pretty big. You don't have to twink the rest beacuse they should'nt get hit.

It also gets easier as you get rightious fury (i think it's 16)
