Playstyles and youth academy in career mode

Playstyles in career mode is kinda annoying and hard to get, as in player career, you have to focus on one specific personality, that allows you to get 4 playstyles, and like after the first season you have to stick with your choice, as its nearly impossible to go back to 50% if you want to change playstyles, maybe like do some objectives like score 200 finesse goals to get finesse/finesse + etc. Maybe allow 2 playstyles at it makes you player greater, and more fun to use
And in manager career, they're just getting a random playstyle +, when they hit 90 rating, so it's impossible to make your players so they fit in the tactics. And the youth academy is kinda useless in higher leagues, could be fun to get the next Lamine Yamal even if the chances are very slim.
And the 5v5 rush game mode for youth players, I think most players don't even use it, as it like waste of time, and you can only play 5 players at a time, which makes the development for the whole youth academy harder. Maybe just do a 11vs11 and add a sim button, to just at least give the academy players some gametime and stats.
