X-Factor cards, bad value

I honestly don't know why I even made Nylander, he just got an 85 but it wasn't performance based and who knows when he gets his next upgrade? I currently have 1.4M coins and I have no plans to make the other X-Factors seeing as there is no guarantee of upgrades  and even if they consistently perform in real games, it seems they don't get upgraded unless the content team decides to upgrade them versus how it used to be, they'd have a good game and they'd get a card. Its a shame really because it makes the X-Factors far less exciting.
