Here are my current frustrations with this year's version, I highly, highly doubt these are due to my managing skills (currently midway through a Bundesliga campaign with Wolfsburg):
All wingers are Messi/Ronaldo in disguise, taking on multiple players at a time before finishing perfectly, this includes my own wingers.
Most games I dominate possession due to playing 2 cm's (1 b2b and 1 BWM) and 1 dm, on top of this I usually have something like 20-25 shots on goal, the other team will win with 1 shot, my striker gets a high rating..
Hit the post 2-3 times a game.
Every game there is a sending off.
I experimented with the match engine by saving before a game and replaying it, without making any changes at all, the variations were MASSIVE, lose 5 nil first time, win 3 nil, draw 4-4... no consistency or anything to indicate that my tactics had anything to do with the outcome.
