If you have some haste buffs, they'll help a good bit with the increased melee hits. Solo, it's not always going to work, but in a melee heavy group, it works wonderfully. However, I never fire it off at the beginning of a group fight, as I want to let the tank gain sufficient aggro in case I get credited with the AM. It can generate alot of aggro if it decides to fire off about the time you unleash some heavy hits.
