Breakfast Topic: Have you used your level 90 boost?

A couple of nights ago, after much deliberation, I finally got around to using my level 90 boost. I now have a very nice hunter that I have absolutely no idea how to correctly play. This actually works to my advantage, because I can mess around with that in my free time without really bothering anyone. That, and I have a class that is perfectly capable of soloing a whole mess of fun stuff, probably. First though, I have to find some cool pets. My hunter didn't have many pets. Which pets are cool, these days?

I still have a second WoW account that I have yet to pre-order the expansion for, which means I'll have another level 90 boost to play with when that time rolls around. It took me long enough to make the decision with this character that I can only imagine how long it'll take for a second one — hopefully sometime before the expansion after Warlords is released. But I'm curious whether or not I was the only one that dragged my feet and waited before using the feature. Have you used your level 90 boost yet? If so, what did you make, and why? If not ... well, why not? Do you think waiting until Warlords is out is the better idea, or would you rather take advantage of the service right away? Which class do you think is the best for boosting, and why?
