dont worry buddy life get much easier soon.. i think you get pull and your aoe taunt in the next few levels. Just when you open on a mob try and get your aoe to hit as many targets as you can(cause if you dont touch them they aggro the healer) I also found it much easier to ask the dps to focus fire with you at that lvl seeing as you don't have your aoe taunt yet. Also if your loosing 1 or 2 normal mobs dont fret the dps should be kiling these to start anyways.
