Just wondering about people's view on the balance T17 2 set bonus and when you give it up. 12% reduced cast time is quite powerful but is it as powerful as extra int / mastery?
My choice is -
T17 2 set bonus or +64 int, +290 mastery +225 crit, -100 haste
Mr robot is putting the T17 2 set above the upgraded gear, but I'm not so sure...
