As I understand it, currently when Mega Man or Bass takes damage, he loses half of his Robot Master weapons, chosen randomly. I'd like to suggest that if MM or B has an RM weapon equipped when he takes damage, he never loses that one (unless it's the only one he has). Why? Well, losing your current weapon is disorienting, and it's a situation that doesn't come up in the original games. Plus, other characters don't lose their special weapons when they take damage, so it's a situation only MM & B have to deal with. And this way, if there's a weapon you especially want to keep, you could equip it before going into a dangerous situation, which adds more strategy to the game.
