I think that's a terrible formation to play vs the diamond. You have your guys spread out and he's attacking in the middle.

In the CL semi's last season I played vs a team of all 6 and 7 star players all with abilities, I am a normal team. He played a diamond, i played 451V and beat him 4-0 1-0. He was an active owner and attended both matches. I'm sure he feels the same way as you do, but that's the thing about the diamond, if you got the right guys you can crush it, but play against it wrong and you get killed.
