This is nothing new but I think most have forgotten about it since Arcane was a "second" spec in ICC(until now).
I did a search and didn't find threads about it. I'm sorry if this is a repost and I'd as for a delete incase it is.
Incanter's Absorption+Mage Ward=Spellpower if frost/fire/arcane damage taken
Global Thermal Sapper Charge does fire Damage to the caster, and doesn't trigger GCD making it a free 300 additional spellpower whenever you can pop Mage Ward along with it.
They scarle with talents and gear btw, as for me they do around 3,4k fire damage back!
Really good as you can pre pop Mage Ward and chop with 300 additional spellpower for 10seconds in the "burn phase" at no dps cost!
