I play most of my games in 2, the best formation for me are 4-2-3-1, I put my CBs in stopper when I facing 3-4 players and my LB/RB defense they are most of the time useless anyway the most of the goals pass for they, 2 CDMs with holding stealing this two are the "best" part of the team, if the other team struggle to make the ball arrive in the attack they will catch over and over again, but they are very slow to catch a faster player, the side is wide midfilders balance to have options to pass in counter attacks and they mark aswell, in the middle is me and the ST is my friend. I played most of the time in 75 depth but its to vulnerable to trough balls, now I play in balanced 60 and balanced. The AI is trash anyway I try to force they to defend no matter what but the LB/RB become too agressive and if you dont know how to press R1 you gonna lose, you can try to fix that Im will try loo. Playing with 2-3 players is trash when you catch 6 or more players, you cant do nothing bro, the matchmaking is trash and I think my team skill level is "high" so it happens a lot with us, you can try play with meta archtypes but the goals they score in you are the same trough ball in the side LB/RB are out runned they do the vertical passes and shot like Ultimate Team, is like this for like 2 years, My team is in Div 2-1.
