looks juicy but that will take a while to get, so getting a big mana pool early on might be a little trickier, but the skill also costs 500 less so it will probably work out. The mana regen mastery looks like cool too, depending what the scaling ends up being at endgame. Also sad to see the reco wand rw with Pagan Rites removed, it was so awesome for weapon switch healing
