I recently reworked my AA spec a little bit. I used to have Dragon Rage in the monk AA tree that would give a hate component to Dragonfire. After a slight rework, I found myself putting ten points into Hostility in the Heroic tree that procs a hate gain a few times each minute. I don't remember how well Dragon Rage helped with my agro control, but Hostility is holding up well enough. Strictly between these two abilities, is one better than the other?
