The new aerodynamics of the Max, if replicated in whatever simulator might have them, might allow you to roll into 45 degree bank and as you pulled , you might not have to pull anymore or pull less because the engines aero effect started pulling for you. What's wrong with that I don't know. If you have a good crosscheck you fly the attitude and performance instruments and do what ever it requires with the stick. If there is any other flight envelope where the old system would be deficient for the MAX and you needed the MCAS we don't know and Boeing isn't telling us but previous threads have hinted that a normal flight would never see it. This is all supposition by me wondering why steep (or step) turns were mentioned in the one of the Boeing blurbs.
