Mate, I suggest that you read the OP.
TFF explained well what happens when you use "Instant Result": your assistant manager might change the roles of ML/AMR positions in the tactic which will reduce the efficiency of the tactic.
I know what he said, i read the post last night thanks and I'd rather have that risk tbh. Its 2 boring when you can waltz thru a season without anyone posing a challenge to you imo.
