I mean it's pretty easy to argue how lame it is that most RPGs just make weapons direct upgrades from one-another, so bad example.
And I think overall he's right, but both of you may have neglected a factor of item balancing, acquisition. Usually ultimate weapons in RPGs require special procedures to obtain and don't invalidate the rest of the game's challenges, though even if they did you could call it balanced if the method to obtain it is hard enough.
The reason you could say BotW's overpowered weapons are bad design is that most of them are trivial to obtain in the right circumstances, and you're all but guaranteed to get at least a few by late-game.
I personally think RPGs have something to gain by looking into equip systems that don't have objectively "best" options, it's one of the best things pm:ttyd did and it feels like most RPGs only dip their toes in meaningful weapon/armor diversity, but I digress.>>473143538
