Definitely a problem. If you can catch the ball coming down the right orbit from a plunge you can just go straight to backhanding. Apparently there's some options/rules to make MB more difficult though, I've heard you have to bash down all the drops and get the ball in the scoop in back or something? Still the same shot though, and we know how tournament players love a repeatable shot. Requiring a random target, or completing a reactor, or something, to relight locks would be much better. Especially when multiball also gives you the score multiplier...
