The point of XP was giving us control of our players development. Also to allow for natural breakout players. If you drafted a 5th round RB last year rated 70 and then ran for 2,000 yards you could have him rated where a 90+ where a 2,000 RB should be. Now you will be lucky to see him go to a 75 after the same type of season.
Maybe EA should have XP sliders for leagues. It's just such a huge change from last year. It almost makes game prep pointless.
