This formation is going to be called "t-shirt" (thanks Khris!) it's one I've been trying out pretty successfully, along with 4 2 1 2W 1, basically trying to use two DMC's as often as possible.
This is too funny. I haven't been logging into the forum lately because I moved (no internets!), so I was checking your team out on the friend's list and I saw that formation. I instantly dubbed it the "T-shirt" formation. LOL
