First thing I do is find mobs around my level or if I have chantra buffs and good armor I find mobs a little higher than me... make sure there is a boss within the mobs... now grab up some agro around the boss and click on the boss... when you get close to the boss hit your aoe spell and continue running... now just keep running and useing aoe untill the boss and mobs are dead... simple yes but I like doing it that way because you dont have much downtime and you wont have to keep clicking or hitting tab to shuffle through mobs...
