I found the beta unplayable due to the goalkeeper injuries, lack of AI subs, unrealistic number of goals, mentoring taking a straight copy of the senior player's personality, and issues with player interactions, amongst others.
After a couple of days resisting playing the full release, knowing that most issues weren't fixed, I succumbed and thought I'd start. Some of it must be fixed, surely?
38 mins into my first friendly, first choice goalkeeper breaks his arm. 70 mins in, second choice goalkeeper breaks his arm.
This thread may as well be closed until a patch is released. It's quite obvious what the core 10 issues are.
