Well, maybe not magnificent, but at least functional and viable in Wrath of the Lich King. Tipster Daniel alerted us to Ghostcrawler -- the blue of blues for Wrath, according to him -- blinking into the Mage forums to request Mages to give feedback about the different trees.
Although Ghostcrawler seems to post her call outs during the wee hours when people are deep in slumber -- or in a drawn-out raid -- we at WoW Insider believe that it's our duty to get everyone in on the action. If you happen to be in Beta and play a Mage, now is the chance to have your thoughts heard on the Frost tree, the Fire tree, and the Arcane tree. While you're at it, give the developers a pat on the back for the overwhelmingly enjoyable Mirror Image.
