My main from 7 months after launch has been my firemage:
Name: Amonhiruu
Level: 80
Class: Mage (Fire)
Race (and Faction): Human
Server: Moonrunner
But, I've been loving my DK of late, and I've got some shammy love too
Name: Sebekamon
Level: 70
Class: Deathknight
Race (and Faction): Human
Server: Moonrunner
Name: Ahoamon
Level: 60
Class: Shammy
Race (and Faction): Dranei
Server: Moonrunner
I've got a level 40 Hunter, 40 Warrior, 30 Druid and a 25 Paladin, but I've not played these in months. I'm grinding on my DK now, and then it's back to my mage to get level 80 epic gear. DK's are really very powerful, and I REALLY hope Blizzard doesn't nerf them.
