The imbalance of the versus mode is due to the director AI. When it chooses to spawn certain types of special monsters, using the same criteria it chooses to spawn those monsters in a normal game, that monster becomes available to the infected team. If one team gets multiple tanks that means the director AI has decided that the survivor team is doing better than the same level where they were the infected got only 1 tank. For better or worse blame the director AI, though it does kinda screw up the balance of versus.
In my opinion the only truly meaningful scoring mechanism would be to let each group play through an entire campaign as 1 side, and them repeat with sides swapped. Whichever team completed the campaign the quickest wins. Maybe add time penalties for survivor deaths. The current abstract and lame scoring mechanism, while swapping sides each round is useless.
