Don't forget about pitcher injuries that screw things up.
We had a blowup in one league, because the guy I wanted to start the game was on an (injured 2 days), and would have been ready to pitch (deciding game of the series). Only he wasn't actually slotted as the starter when the time came... it was some lefty who was clearly my worst starter. So obviously, the 5 PC thing came into play, although my opponent tried to act as if I was gaming the system to take advantage of a handedness advantage.
Of course, unlike Tec's drama, this problem should be relatively easily solved. ... Just don't let pitchers get injured in the playoffs.
