It seems that one of the biggest problems on the WCS servers is the lack of a good auto-balance program. Time and time again, one team just completely dominates the other. The winning team is getting all the money, so the cycle just becomes stronger. The solution seems so easy with an auto-balance system that moves the top player to the other team. I don't know what it is like in the other servers here, but in WCS the problem is giant; and scores such as 10-1 are common.
Balanced teams would make it more fun for everyone. Right now, it's very often 1-sided.
