After reading about the Haste > Mastery > Crit build I decided to try and reforge to it using AMR.
However the only builds it really gives is Haste > Crit > Mastery so using the Advanced part to adjust the weights but it seems to take the Red Agility Gems off in favor for haste or haste/exp gems.
Is it a problem of how I am prioritising the stats or something that is out of my control?
