First of all RINALDO RESPECT!!!
If it weren't you and your tools Fifa series wouldn't be so much interesting for million of gamers.
It's a pity that you could not finish the CM12 , cause FIFA 12 is the first good football game of the series.
But if you intent to make an upgrade for CM12 , I would ask you  to consider some requests .If possible...
1.If it's so difficult to add new leagues could you please add only the option to edit the existing ones?
I was thinking if this is possible we could, for example, replace the teams from Ireland league with teams from rest of Europe (APOEL , Dynamo ect) and assign them into European Cups.In the same way, we could replace K-League with Argentina League and Austalia League with teams from South America and replace K-Cup with Copa Libertadores.
2.Can you add the CMP option?
3.If  the Turkish League and Czech Leagues exists into the game data,can we use them as leagues that we can replace them with created ones?
4.Finally, a rather silly question...Instead of creating new Leagues, if we copy the data seeds from a league existed already in game ( eg Premier League  ) save and then assign teams crests ect under the 5 magic ids could it possible to have career mode for them?
THANK IN ADVANCE AND GOOD LUCK WITH WHATEVER YOU DO
