Changes I'd like to see (off the top of my head, noting that I have PvP in mind): Polymorph no longer heals; in fact DOTs should remain in effect while polymorphed. (Just like every other class's CC spells.) Reduced casting time would be nice, but now I'm just getting greedy. Pyroblast needs a buff. For twice the casting time it ought to do significantly more damage than Fireball, and it doesn't (in fairness, the DOT component is better: 268/12 vs. 72/8, but that's dispellable). Up the mana cost and/or cooldown to compensate. Invisibility. Always been a mage staple in Warcraft games. I don't buy the argument that it's too hard to balance an invisible damage dealer, since the game already has one. Boosts to mana shield. Maybe just including higher ranks through drops would work. 540 dmg absorbed is nothing to a epic gear rogue who can backstab for 1800.
