It's something I've definitely noticed and am giving serious thought to right now. I've been watching the HLstats graphs over the last week and do notice a similar trend. This is further supported by TF2Stats showing that doublecross falls a LOT lower on the popularity rating than 2fort. I think we'll do a trial separation and see how it goes this weekend. 24/7 doublecross basically flatlined, I'm going to change it to 2fort and see what happens.
