Yes a DC who also can play DMC would be nice. But fact is that i've never used DMC so far. I know it probably will come in handy, harder opponents i need to face. But since i am mega favorite each game in lvl 2, i dont feel that i need a DMC. But you are right, it would be good to have one atleast just incase.
I rather play 3-5-2 or 3-4-1-2.
