Circle of scorn, flash until mobs are dead, use riot blade combo,ether or bard song (if you have one) to keep MP up, when mobs are lower in number spread RoH combo around, pop cooldowns as necessary.

I disagree that pally is 'pathetic' at AoE aggro. while i feel warrior has to work a little less to keep aggro on groups i think this is intentional as warrior has to work harder than pally to mitigate damage against them and while pally contributes much less to AoE dps it's made up for with flashes blind effect and simpler damage mitigation to survive a little longer rather than helping mobs die faster.
