I played my opponent today who was using the 4-4-2. He is currently first in the league and I was second. (I am level 9 by the way). I won him 2-0 using 4-4-2. I normally use the narrow diamond, but for this game, I decided to play 4-4-2. His team is slightly better than my team. So you can certainly try out 4-4-2
