I really wish there was a game where you could level up and make an interesting choice or two, but realistically, if you have advanced knowledge of the options then your choices are all made at level one.
Like, I wish I could play a fighter for three or four levels, and then choose to pick up a little arcane or divine magic as the campaign evolves; but if I really wanted to do that, then I should have been planning for it all along, or else I probably don't have the right stats or synergy. It's hypothetically an option (if it's allowed in the game), but in practice, any option that severely hinders your efficacy is not really an option.
