I have a couple of Mages but only really two notable ones. Celliu is level 90 and unfortunately abandoned on a server I don't play on anymore. She along with my five other 90's on that server got a bit of a treat this week with the release of patch 5.4 and what's now being referred to as "Super loot island!". She was previously geared in mostly quest rewards from MoP but is now sporting an almost complete set of 496's. I love the Mage class but I have no real ties to Celliu, she's just another character. One who I leveled with Recruit a Friend during Cata who somehow bumbled her way to lvl 90.
Instead my heart lies with Korlat.
Korlat started life as a Human. She was my first real alt during Vanilla. I made her to take a bit of a break from my Warrior from time to time. I made the mistake of putting her in the same guild as my Warrior. As I mentioned in my Hunter week post when I was online I'd often be asked to tank instances and this was the case when I played my Mage I'd be asked to relog to my Warrior to help people.
I got her to around lvl 30 but I never really got into her. One afternoon a friend was running a guildy though Scarlet Monastery as they were a mail wearer I asked if I could tag along to snag a few of the cloth drops. At that level I wasn't able to equip any of the items I'd gotten so I decided to level her a bit more. At level 40 I decided to change spec from Fire to Frost and something clicked. I loved it! After having struggled along for 40 level's she was lvl 70 in a matter of days. Every Mage I've lvl'd since has been Frost. I do enjoy Fire a bit more but only in a raiding enviroment.
Late into Wrath my guild decided to transfer to Horde and my Mage was one of the first characters I moved across. I'd join the odd pug for ICC 25 on the weekend and often be in the top few DPS which is something I can only achieve on Mage and Hunter.
When Cataclysm released I level'd her to 85 but she hasn't gone any further as again she's on a server I no longer play my main on. I do plan on leveling her to 90 in the upcoming weeks. I'd love to see MoP from a Horde stand point.
If I'm honest, my heart not only belongs with Korlat but with the Horde.
