Newbie at level 2 and got my head kicked in by team with DL DC DC DR DMC AML AMC AMR ST ST.

For the moment, I've had the most success with what looks to me like a dotted V formation . . . 4-1-2-2-1 (DL DC DC DR DMC MC MC AML AMR ST). How does one take advantage of a team that overloads the front and back at the expense of the middle?

As a side note, how does one message another player to tell him his formation is illegal and that's why he's losing games he shouldn't? I don't think he realizes that he's getting killed on possession time.
