Do we need Sub-weapons?

yes the godshield is broken, sos the crissaegrim, but i actually want something cool and op like that in, for one simple reason

you dont HAVE to use it

there are many op things in Iga games, and if you were forced to use it it would make sense to ask for its exclusion, i for one welcome those broken combos because if i want to use it its there, and that also encouraged experimenting with the game, if nothing in a game interacts with another then it devolves into what has the best stat and is the enemy weak to it, hell most rpgs the elemental weakness is so minor i end up using the most powerful weapon i have and mash attack a lot because theres no point in strategy if you can just beat it to death with the biggest hammer, rinse the blood off, and repeat the whack a mole minigame again

anyway, rant over, as for subweapons i dont see the need for them to be a separate mechanic entirely, but having them be an extension of the magic system like DoX and PoR where theyre like a secondary attack instead of candle fodder you have to go halfway across the map to reacquire
