You can also pull a guard when onyxia's even happens in SW Keep and pull him to the AH, then hope you get lucky and he does his AoE
I died (you end up with so much aggro compared to the people who are just now hitting it, you are going to die) and when i ran back there were about 12 dead bodies just sitting around. Not nearly the results of this, but its fun and doesn't involve much effort ^^
I ice block, that ends, ice snap-ice block, and still end up dieing in the end :P
