For the Beard and Eyes Thing. First of all you go to Become a Legend, Start a ne game, then choose the player you want to change, and when you come to the main menu of the mode there you must go to the place where it says "Save Playerdata" when you save playerdata you can save the player data on one of the players in the created players section or save it there as a new created player. When you have saved leave the BAL game ,go back to the Main Menu, go to edit and there you will find the player from BAL Mode in the created players section. Choose this player and now you can edit this Player. For example you can now go to Eye Colour and change it how you like. and you can give the preset player a beard, just like when making a facebuild. You can change the other parameters also but as far as i´ve seen it they don´t change anything. So now you have created the same player with different Eye Colour or Beard.
The final step is then to choose the original player you wanted to change and there go to base copy. there you choose the changed player you just created and accept. Now it is finished. If you didn´t play any BAL matches with the player before saving Playerdata stats and everything should be the same
Hope this helped
