I would like to see more flexibility in player career mode development.

Specific points (Heartbeat/Maverick/Virtuoso) are added based on performance in matches.
The skills that can be acquired are limited by personality type.
This means that the skills that can be acquired are limited to a certain extent depending on the position.
It is not possible to create a player who can make powerful and spectacular passes with tricky moves.
As a CAM, you can make elegant passes and set up goals for everyone.  
But wouldn't that prevent Maverick from developing, making it impossible to perform tricky moves?  
I want to create a dream player who possesses all three: Heartbeat, Maverick, and Virtuoso. Even if it's impossible in reality, it should be possible in the game world, right?
