The B-Wing as written can still do that. It's clunky, but a good pilot can leverage those shields and big guns. It isn't supposed to be a super fighter, but rather a fast assault bomber that can also dogfight in a pinch.
The Defender is the real concern, but there's not much that can be done about that and keep it balanced except for, maybe, making it hyper rare and not allowing the PC's into it.
