Currently specced into Primal Elementalist + Elemental Mastery, so decided to run a Simcraft to find out about the weights.
However it turned out like this:
Int: 3.93
Haste: 1.35
Mastery: 1.47
Crit: 1.61
In all honesty I'm a bit sceptical about reforging like simcraft suggests, which is why I'm trying to get some feedback here
Thanks!
