So what prevents someone buying a really cheap class with a high cost reclass option and then immediately reclassing to the higher cost class?

Because the more expensive ones aren't actually better, you must be LVL 10 to reclass, and if you just pick some bullshit as the first class, you're gimping your character. If I may make a suggestion, I would take the Mercenary as a reclass, they get a very good skill at LVL 1.
