1) i hate those games where you have to "train" players or teams to get them better - please don't do that.
2) better stats! there are great stats in competition mode - why aren't these available straight after, or even during, a friendly game?
3) option to alter rules, eg, injuries on/off, 40/20's on/off, maybe even players per team could be changed.
4) players can simply place the ball to score a try, instead of having to dive!
PS - in my experience, forward passes never happen unless you f**k up.
