Squad Battles too hard

There has been patches so you might just have to get used to it again. 

Don't know your formation or tactics, but will kindly suggest mine.  Try using tactics code mk?$99LuwDK. It really helps to have players with role ++ if possible.  Find it easier to score on legendary, only play world class against teams rated 88 or higher AND chemistry 30 or higher. Play lots of pinged passes, spread the pitch by dribbling out wide, use pass and go in and around the penalty area, but most importantly shoot as often as possible and force saves.  This helps you stay on the front foot and you can almost feel your team having momentum.  Defensively, always press the ball manually with your attackers, use your CMs to mark only on their half of the pitch and help your FBs. Use your FBs to cut off angles for cutbacks and force cpu wingers to the touchline. Don't dive in for tackles excessively, instead press x rapidly when near opponents. Counter ruthlessly, especially after corners, because this is the best way to get quick goals. Also if possible, be sure that all of your defenders (especially fullbacks) have at least the regular bruiser playstyle. I get 30000+ points weekly (with the exception of disconnects) so I really hope this helps you. Wishing you success in game and in life 

Thanks a lot I will try this. Best wishes to you as well.
