Give this a try. My buddy and I are only a 2 but the bots played sooooo good when we changed to this and just put your human players where you want to within these tactics:
GLK Sweeper Keeper
LB and RB Fullback Versatile
CBs Defend Defend
CDM1 Deep Lying Playmaker on Build Up
CDM2 Box Crasher Balanced
RAM and LAM on Half Winger Attack
CAM Human on Playmaker Balanced or Roaming
ST Human on Advanced Forward Support
Defensive Line 61 High (the bots will pressure the ball without being too high, instead of standing around picking their butts))
Passing Style Short Passing (Bots will be less likely to just whack it up the field mindlessly)
