The emphasis on expensive almost makes me think that spot healing on hybrids will be an issue.

So if they increased the cost, effective in todays terms, for a heal by 300% off spec. Combined with something like buffing resilience, perhaps making it 30% more effective. This introduces more drain, diminished returns, kite and crowd control back into the game.

They also like the gimmicks on masterspec, so more bubbles / guardian angel (reset fight, second chance) like effects i would think, less mutilate v3.0 and more utility.

Makes me think of ret paladins and shadow priests where damage is healing coming across great.
