I'm not sure if anything has yet been done about the star scores for teams. I pointed out a long time ago that although this game shares the Fifa 5 star rating system, you can't actually make any 5 star teams, no matter how highly players are rated.
Now we obviously don't want teams all over the shop rated 5 stars, but to not have some of the best International sides and World XI type sides able to be rated over 4 stars is just a bit unusual.
I've tried to edit Australia for example to make them a 5 star side and the highest I could get them via player editing was 4 stars. So, I upped a few more stats in certain areas and they went down to 3.5! It makes it hard to create proper balanced sides and because of that I gave up editing a couple of months ago at that point.
Please tell me this will make the final patch, because when you really think about balancing out attributes, there shouldn't be these kind of anomalies and it doesn't engender a huge amount of confidence in the statistical quality of the rating system.
