I just hope to get rid or tweak the damn morale system. The handicap system too. It's crap. FIFA is touted to be most realistic, yet for some reason if I concede a goal, all my players suddenly **** their pants and become retards, or if I play a weaker team, suddenly all my players are 80 years old with the reactions of a snorlax, and the other team is on cocaine.
That and the obvious fluff. Better commentary, better stadiums, better presentation (ala PES Champions League stuff, with player pictures in the lineups), tweaked Manager Mode, etc.
And I have a feeling this impact crap is just going to be that, crap. I can just see it now, little touches making players go flying, perfectly good runs ruined as a player does a barrel roll.
