It has been suggested by some who've played this way that it's inadvisable to make a ball on the break as the one pushing out is, on average, at a slight disadvantage. If so, the break would remain relevant.It would certainly make the racking and the break shot nearly irrelevant. For many, that would not be 9-Ball.
Personally, I think it's worth a try in a significant event.
The premise of this thread is that the excitement level at the China Open was reduced because alternate break meant nobody could run packages. Yes, off a dry break, a player could run two racks, but that's the max. Seems to me that adoption of the "mandatory push after the break" format, which would make even two racks run in one innings impossible, would reduce the excitement level even further. Fans love seeing the pros running packages!
Taking extreme measures (with the most obvious example being call shot call safe 10ball) to try to eliminate the luck factor in pro pool rarely serves the interests of the fans. Event producers that ignore this probably deserve to fail.
