Should this even be legal in a game with pvp? It was so overpowered on console.

It's not THAT big an issue considering it takes another unit to do the whole thing, but if you really wanted to you could just make it so neither unit can trade their currently equipped weapon while in battle. That doesn't really matter for the active unit, but it makes it so the other unit can't be wielding a different weapon after already ending their turn.
