14: Arcane Explosion. Now you can AoE
16: Flamestrike. A slight improvement to your AoE rotation
20: Blizzard. You learn it at 20 but you can't really use it yet.
22: 3/3 Improved Blizzard and Rank 2 AE. A great level!
23: Cold Snap (talent). Use it to re-nova when you get resisted.
26: Cone of Cold. Makes your life a lot easier. Or not, since it's less reliable in Classic.
28: Mana Agate. First mana gem. Yay!
30: Ice Block. Not a big deal, but nice to have.
40: Ice Barrier and a Mount. Easy mode.
You learn a new rank of an AoE spell every 2 levels, so each one gets updated every 8 levels.
14: AE
16: Flamestrike
18: Nothing (would be CoC)
20: Blizzard
22: AE
24: Flamestrike
26: CoC
28: Blizzard
etc.
