I don't think the random witches are all that game breaking. I am used to playing on the more difficult co-op settings and so when I come across them in versus they feel like paper tigers.
If the game were scripted as far as where weapons were located as well as the witch spawns, it would in favor of the people who played the infected the first round. They would know the weapon spawns and go right for them, as well as stock up on molotovs for the tank they knew would be spawning. They could throw down the fire right where he popped, when he popped and book it. He wouldn't have a chance.
It would, however, be nice if the director noticed the scores and threw the occasional extra witch at the people who were winning, or even hid or withheld the random weapons you come across.
