It's this way for a reason, to make it challenging! If the first hit in the chain had a multiplier, nothing would ever be in danger of leaving your grasp and would make tanking succesfully a lot less satisfying in my opinion. When I'm grouping with a couple of good dps, I need to plan out my hits in order to maintain aggro on all mobs. Do I skull sunder (200x3) this mob before the healer takes aggro? Do I butcher's block (280x5) the main target or am I good to go? Garuda's add is about to spawn, better plan ahead and save up a Butcher's Block for instant hate!
