Don't use the 4-5-1v... that doesn't fair too well vs 3 strikers, you could use the DMC elsewhere like a ST or AMC, which is why a 4-2-2-2 hex may be an option... You could always trial it too if you have 2 accounts with similar qualities
I made 2 new accounts to test formations and tactics on and I had the upper hand today in my league match but couldn't find the net.
