Mages got some very interesting changes. Apparently Blizzard finally listened to all our hollering on the forums about how terrible our level 90 tier was and actually gave us new spells instead of that recycled stuff. Living Bomb isn't going to be baseline, it's going to be a choice of interesting Arcane and Frost flavors of it at level 90. Cauterize also got a weird mix of nerf/buff. The recycled nonsense that was mark 1 of our level 90 talent tier is learned with specs now.

Also, it looks like Fingers of Frost is a learned Frost passive. It was missing from the previous calculator.

I don't see Blast Wave anywhere, I hope this is just alpha weirdness and not the removal of a nice instant AOE/Snare.

Blastwave missing, no damage component to Deep Freeze, Fingers of Frost seems to be PvE raid only, FoF and Brainfreeze no longer working together. I fear for frost. Things are looking up for fire though, Dragon's breath back to Fire baseline. Digging the new Ignite.

That should pretty much cover everything, I think.

^ The article this one could've/should've been.

Blast Wave has been rolled into Flamestrike, which has returned as a level 70 class ability (it was missing before).
