If anyone has a way to fix this problem that would be great. queue times just keep getting longer
No I'm afraid not. There isn't anyway to manually disable DLC maps through Battle.net. However, those populations are already basically set just between two groups, those that own the DLC maps and those that don't. That should be easier to deal with now too after the implementation of Party Up, which allows players to host a party and share those maps with their friends.
