Ran 1-5 last night, did my usual double Bane on spiders -> Miasma 2, then spammed Blizzard. Towards the end of the phase I burned my last Aetherflow charge on ED and Aetherflowed, put me back up practically to max mana. (I usually always burn a charge on ED in phase 1 simply to avoid running out of mana in phase 3, but with no thunder now, it may not even be necessary) Spamming Blizzard did not remotely run me out of mana.. with a good group, the AoE should be strong enough that you don't get more than 3 blizzards in before it is time for phase 2.
