hmmm, you're right about 3 DC's and about DMC. well, i would try something like 3-1-4-2 (ML,MC,MC,MR) or 3-1-4-1-1 (ML,MC,MC,MR)... if it doesn't work, try to put arrows UP on ML and MR..try to play defensive on counter attacks, but hey, it's your choice this is just my formation and how i would play, so don't believe me 100%
tell me what result it was and what tactics did you use
