Well that would depend on exactly how much of a disadvantage to the ghosts the player anticipating the ghosts is. In the original Pac-Man it was possible to predict the ghost movements accurately enough to for books to be published with the exact path to follow through the maze to guarantee a victory. Essentially this means the pridictableness of the ghosts was terrible disadvantage for them. Adding a just a bit of randomness, enough to distrupt any preplaned path, but without making the ghosts too "dumb" may not be a bad idea.
