Tukkun, I will be entierly honest, I dislike the way the new boost system works. It doesn't seem balances. I loose a lot more progress boost than anyother at the moment. I would suggest you go back to the previous system untill a nice balance is reached.
The game refuses to play for me.
I try to play a career and nothing works. I get straight to a match with an "undefined team" where none of the buttons work other than pause. Quite frankly this game is ridiculously bad..
