For those complaining about the player ratings going down, it will only change if you go to the player's skill tab. The overall will show the original one for a brief moment, then change to that number. The fix to this is to just slide the slider back to the original rating (use SOFIFA.COM for help)
Don't worry about editing team formation. It will show the unoriginal rating but let it be. It won't change in-game unless you went to skill tab of player and not reset the rating
The only problem would be resetting all the one club player and team player traits. Most important players will lose this trait so if you're playing for Barcelona and see that Casillas wants to leave madrid or if you agree to sell puyol, xavi, or iniesta and see them go instead of staying, that's the problem...
And, Higuain, Nani, Robben, Balotelli, and Robinho will have one club player traits which they normally don't have, so that means they will stay with their clubs FOREVER!
FIX THIS BY YOURSELF.
Chelsea did not deserve the win. They played anti-football. It would destroy the future of football. Barcelona or Bayern deserved it.
EVERY TEAM has their own cheaters. Divers, horrible tacklers, hooligan-like players, etc.
Chelsea is a pathetic excuse for a football club. All money, no history, no class.
About career mode, it's possible to modify those images which appear on the screen.. I mean those ones with player celebrations(if you win) and so on... some teams have a lot images, but some have only generic images with only a blurred image of a crowd... I want to add more images, how to do that? I hope you'll understand what I'm saying. My english is not so good.
and do you know what is the standard face number in CM12 of player who was creating in game ?
I believe the database has a createplayer table. Maybe with database master you could edit your created player, Though I find it rather useless creating players ingame since you can do that with the editing tools
