Duty Finder -> Switch class?

[Kitya]

Not switch in the instance, switch at the "commence" screen. As it is counting down, it would not let me go to my original class then hit commence.

EDIT: So crafting works huh? Perhaps I should suck it up and start knitting. I have a macro for Dragoon and Bard in my respective hotbars but it gave me some error message, not allowing me to switch o.O

Yeah, hence the edit. I derped because I'm working on heroic progression in WoW while foruming!

Anywho, you should be able to switch your class when the queue pops. I do it all the time, queue on my main class and then level a baby class for fun. I've never had issues with switching when it popped.
