Since this problem has persisted for so long, I figure it deserves its very own fresh thread.

The critical strike increase with building storm when spec'd into favorable conditions in the stormcaller soul tree is working as intended and is providing a 20% increased chance to crit with hypothermia causing spells per stack. However the 100% damage bonus is incorrectly, according to the tooltip, not being effected by favorable conditions and the damage bonus only receives a 10% increased chance to occur per stack of building storm. This is causing roughly a 3-4% lose for mage single target dps at the moment, and lord knows we need all the extra punch we can get in this area.
