i just don't think the auto contest will be as much of an issue...i feel that the "weak" hand up animation won't affect the shot nearly as much as a "block button" jumping contest...so a person who can master the block button contest will still have an advantage over someone who only relies on the "auto contest"...the more skilled user still has the advantage...so, while this system is not quite ideal, it still works for me.
what i'm hoping is that they've updated their contest system so that doing a momentum jump into a shooter mid shot will actually result in a foul...i somewhat disagree that the "straight up" shot contest doesn't affect the shot at all...i felt like i could affect the shot with that animation (though not as much as a momentum jump contest).
