I personally think a full on revamp would be nice. Combine fire and frost to make an elementalist tree perhaps? Then add in a tree that would have more of an abstract magic focus as opposed to the mage who can only cast one type of energy and/or physical matter. Perhaps leave fire and ice and then work the arcane tree into said abstract magic tree. Perhaps I'm just jaded at seeing so many games turning magic into "Fire, Ice, Wind, Earth, Life, Death"

Dear God, no. No major facelift. That would fucking suck.

Every mage who says something like that should be forced to read the Paladin forums for a day. You will thank the Sunwell, Archmage Pants AND Raptor Jesus our class has largely been left the hell alone.

Ret pallies cry themselves to sleep at night to the sounds of "Holy Power" being whispered in their ears by Yogg-Saron.

Kylene beat me to it. You guys seriously need to look at what happened to some of the other classes that 'seemed to be too simplistic'. Would you like to have an arbitrary new resource to manage? Or how about slapping on a ton of new spells just for the sake of having new spells?

The beauty of arcane isn't its simplicity. Knowing how to manage your mana and use it properly in each encounter is the difference between a truly good arcane mage and one who complains that it's just one button DPS. In almost every case, the latter mage is not maximizing her/his DPS.
