Thief was most tempting because right now I am mostly collecting pets because they are indeed shiny. But I wasn't sure if I would get bored of that eventually and regret focusing on it, since pets don't seem to.. do much. Mage and Healer seemed most helpful to the party but my current party doesn't need much help so far. Hmm.

And I had not realized that you had different equipment options for different classes! Maybe I will wait to pick a class until I have bought all the warrior gear. That sounds like a fine excuse to put it off.
