scientist and constructor really need some kinda of "weapon" to defend themselves
like sure scientist has deflector, but that only works on bosses with ranged attacks (which are only Medusa, Kaje, Penth and Sky captain) meaning with other bosses like ephi, rotondo and badspot, he has no way to fight for himself.
and constructor just flat out has no weapons at all, you cant even fight back at all unless you have your turret, which tends to cause constructors to just kind of turtle in the arena.
like even a weak pistol or the shotgun is fine, just give them some form of defense.
