Imp. Fireball and Imp. Frostbolt damage coefficient changes

[Concillian]

I don't quite understand rage machanics, but does this mean that warrior rage gains are dependent on current weapon speeds, as in, they are calculated dynamically and not calculated off base weapon speed (and therefore scaling with attack haste)?

Yes, it's dynamic.

It used to be that when under flurry, you got 30% faster attacks and therefore ~30% more rage. The normalization formula takes "instantaneous" attack speed, so the rage gain is scaled down... to the point that it gives somewhere on the order of 5% more rage when flurried, even though you are doing ~30% more white damage.
