Im not inactive. It just not worth the effort to do so many task every week to only upgrade a stat once per week.
I always come back for the team camp and get my exp. Bald Guy have the highest exp of any recruit in his draft and probably have the highest +- too, because that's how my build work.
I could always upgrade skating and ck, but ck = a lot of penalty , and sk = change in player decision, which are ,imo, more important than even the stat.
I could almost argue my build is done and im just waiting for the exp. Just a shame my team don't use my player as leader, because my leadership is currently wasted TP
