Observing a few times, seems like uncommon hordes, when used strategically, do become quite the force to be reckoned with. It's almost like having an 11th player on the field. Next update will restrict hordes to be spawned in one at a time to buffer out the appearances. Players can, however, chain them together, but the change will rely on the infected team to communicate to chain them together...or to keep checking the buy menu for when they're available for purchase again. If they still end up becoming a bit too much for Survivor teams to handle, a 15-30 second cooldown will end up being implemented. Also, I had a stupid idea. What if whenever a player buys something, the cost gets evenly distributed to the other team. Geez, that'd make no sense to do, lol.
