Beware of the man who works hard to learn something, learns it, and finds himself no wiser than before... He is full of murderous resentment of people who are ignorant without having come by their ignorance the hard way. -Kurt Vonnegut, "Cat's Cradle"
It's a moderate buff, is it going to be enough to justify a nerf, we will see later when we acquire more gear and see how scaling goes. Otherwise there is some evidence from raidbots for example (http://raidbots.com/dpsbot/Overall_D...14/60/default/), I wouldn't call it fact of course, but as it is now Fire is leading the pack, but the margin is not huge.
