Why does the party need to be balanced?

That's... even more absurd than I expected. Yes, "Chewbacca Defense style non-sequitur" seems about right and I don't see what bearing it has on the imbalance that'll come up during actual play.

He brought it up as an example of a normally “weak” class able to do god-wizard-esque stuff. There’s a meaningful point there, but it also very much does not address the main issue that I and others talked about. It’s a cherry-picked example, but not an outright distraction argument.
