CL Match, confused a bit about opponent formation.

So I've hardly managed to win the first match. Next opponent uses strange tactic formation:
4-2(DML,DMR)-2MC-2ST.
Is this legal formation and if yes, how it should be countered? Flat 3-5-2, 3-2-3-2 or else?

Good idea 3-5-2! attack through the middle. Up to 2MC.

So this is legal formation I presume?

I don't know.
