I already used mine months ago. After having gotten back into Wow with a friend following the Dan videos, we both commited to playing Warlords and eventually both got the preorder. I wanted to try a Mage but didn't want to be thrown into the deep end, having to learn absolutely everything, so I leveled one up to lvl60(!) so I could get familiarized with the class and get the veteran boost to some professions I wanted to have.

It was sill kind of a jarring experience because I hadn't even leveled my main up to 90 at the time, but I got used to it over time and she's become one of my favorite classes to play.

Did it months ago as well and also on a mage. Got four 90s ready to head to 100 now. We'll see if I'm bored enough by the time I'm ready to level that fifth character and just buy him a seperate boost...

I used it on a Hunter I had got to 60 to max engineering because I never have had an engineer. Most likely I will be playing my Monk or my Death Knight (haven't decided, both at 90. The DK is a fresh 90 and the Monk is raid geared) though, not the boosted Hunter.

I used mine to get a warrior. Now I'm one step closer to having one of each tank class! ...Well, 2 of 5, and a lvl 70 paladin. Half-way.

I'll be using mine on a Dranei Shaman so that I can actually have a level 90 Alliance toon for a change. I will be leveling my BE Pally first and then maybe my Undead Lock. Definitely boosting an alliance toon to see the other side.

I used my boost to get a hunter to 90. I just came back to the game with some of my family after not playing since vanilla, and ended up on a new server, so I boosted Hunter which was what a raided as back in vanilla WoW.

Thinking mage, some kind of caster for sure. My main is a Fury Warrior.
