do your job quest, defiance is a skill that will change your tanking... believe me, you won't have agro problem and since you'll generate a lot more of emnity you'll have to hit the mob way less... sometimes, when i'm tanking, i have so much advantage in emninity that i can simple stay 5 or 7 seconds without using any abilities to regain some TP... early levels tanking is simply a PITA
