Sometimes I mog my alts just to make consumables! Got this idea from someone on an MMO-Champ post. I wasn't able to replicate it to a T, or to something that I was 100% happy with, but I wanted to mix things up a bit and just worked with what I had or could get from the AH. I'd love to change the boots, tabard and off-hand, but it will do for now :)
My latest alt, Xenophontis, my little alliance mage. She's furry and adorable, and even though she's currently only level 31, we've spent a little bit of time mogging already.
My deathknight was almost a main change. When Wrath came out, I secretly leveled her before my paladin for the first couple of days. However when I went to ask my guild if I could change mains to her, I got told no since we already had a few people that were changing to DK. I guess it worked out ok in the end! She was my baby in the beginning of Wrath though, we had a flipping blast in Naxx, and she actually helped get a few people the meta achievement for the Plagued proto drakes with our weekly runs. She's my only Bloodsail Admiral toon, and I'm posting her other RP set because I like the way the colors contrast her dark skin :) I'm also afraid to take her out a little because of her residual "Doomsday Messenger" board.
My little brewmaster was shortlived. I went hard for a bit, but as soon as I kept getting queued for Utgarde Keep over and over again we called it quits, and she's been stuck at 70 since. Someday my little furry friend!
I'm fairly certain if I wasn't terrible on my warlock and played her more all I'd ever mog her to is tier sets. I mean eventually I'm sure I'd mog her to something else... She originally started off as a goblin, but when I brought her to Ner'zhul I changed her to undead. She's so cute ^.^
Greenleigh has been one of my most favorite alts. Fun fact: I originally leveled her during Ulduar when Honey was getting annihilated by resto druids. If it wasn't for ToGC going as well as it did, Greenleigh would have become my main character >.< She was always a blast to heal on, and while I missed her old Tauren self for a while, she's pretty cute as a Troll sometimes :)
