So I'm doing a Crystal Palace career mode and am 32 games into the second season. Over that time Bolasie, Sako and Scott Dann have all made at least 50 appearances each. None of them have grown in any stat by a single point. I understand that they're not the youngest but all 3 were first team players for a good bit of the first season to no avail.
By comparison, Yohann Cabaye has played no more than 30 games total I'd say, yet at 31 years of age has grown by 2 to an 81. Meanwhile Jordan Mutch starting every league game bar about 5 has grown 2 to a 74, and only by me training him.
The system makes no sense whatsoever. Unless you train a player up they're pretty much damned to remain at their current overall unless they're randomly chosen by EA to improve (like Brek Shea in my Stoke career last year who grew to like 78 without playing a single game, having little potential and never going out on loan), and player's performances are not reflected in actual in-game statistical growth.
It's become a real annoyance for me that while I've brought Connor Wickham for example to an 80, a growth of 8 in just under 2 seasons, all bar 1 of that overall growth was down to me training him, despite him finishing as the 2nd highest scorer in the league year 1 and is again top 5 this year.
I presume others have had similar experiences, and I doubt there'll be anything done about it, but I just had to vent because apart from this frustration career mode is now better and more enjoyable than it has ever been. The Legendary AI do their best to make every game a 0-0 but that's another issue and it can be played around in a way that this simply cannot.
In conclusion, the end.
