Class Changes:

Mage

There isn’t much to improve on for the Fire and Frost mage specs in vanilla - they are tightly designed and synergize well with other mages very well. That said, Arcane falls far behind despite having an opportunity to fill its own niche, and the possibility of encouraging the Elemental Mage playstyle.
