Player career mode.

Starting as a 71 rated player is unrealistic. How can I play in league 2 and be a 71 rated player.

the only way to start low is by picking a Gk or defender build/playstyle and picking a attacking position which would allow you to be a Low rated player. 
allow us to pick what traits we want. 
I only like the technical trait, occasionally quick step and rapid if I’m a winger.
