So I've recently been picking up some extra crit pieces from Siege. Rocking Titans Grip with 2 Normal Greatsword of Pride's Fall with 38.72% Crit rating and 31.42% mastery. Been running myself through simcraft and it is showing Mastery as having a higher weight than Strength.
Strength is always around 4.75 while Mastery is always around 4.85. I can see how this would be the case with high levels of crit but is it really already? In that case gains would be made by enchanting gloves and wrists with mastery over strength
