Two additional changes have been made to the upcoming mage review. The talent calculator isn't updated with these yet, but should be soon. So for patch 1.11, expect the following additional changes:
Winter's Chill: Will now increase crit chance by 1% (lowered from 2%), but will stack up to 10 times (from 5).
Improved Scorch: The fire vulnerability effect has been increased to 30 seconds (from 15).
