I'm going to tell you what I do when I face a stronger opponent. I play 3DC-3DML/DMC/DMR-2MC-1AMC-1ST.
Orders: Defensive, middle,long,ON,low,normal,zonal,OFF. Arrows down: 3DC and DMC. Arrows up: AMC
The rest of the team stays unarrowed. This has been working with me, but it doesn't mean it will work with you.
But if you can't play with that formation, try to play with 4-5-1V
Regards
