If you've already played WCWS, you've likely been playing for a while and have won a replay. This may have been done to keep average game times down. It makes you shoot the ghost target, which is always risky.
I do find it amusing when people complain about things they have control over. 'It sucks when you stack multiball with loopin supers.' I doubt most of the complainers ever check how many ghosts they have via instant info. If you have no strategy on GB, it's going to be more frustrating.
