Frost Bolt heal, unfinished exploit

[Strath]

So I was in TOES today and casted frostbolt on my mage rightwhen Tsulong changed from hostile to friendly. My cast went off and midway it changed to a heal. Perhaps someone can find a way to have mage healers again?

Also if you cast Frostbolt on players affected by mind control on Garrosh fight and if it lands on players after they are released form the MC then your frostbolt is gonna heal them instead of damage them.
