Let's use this space also to share our ideas about best way to play Score Match!
I use mainly 4-3-3 (sorry for guys still unable to use this formation!) with this configuration:
SPEEDSTER - PROWLER - INTRUDER
ENGINE - PRODUCER - ENGINE
EXPLORER - GUARD -GUARD - EXPLORER
I don't use HAMMER. INTRUDER loses a lot of balls on the wing, but he's useful for long runs.
PRODUCER in midfield is not involved so much in the game, but I have not found a better position for him. I tried also with ARCHITECT, but more or less same gameplay. ENGINEs in midfield are very useful to tackle opponents before defenders.
I don't know if replace a GUARD witha PROTECTOR.
Best regards and happy playing from Italy!
