The problem with the sim is, that it produces too many 100% goal chances, which conversion into a true goal is then artificially prohibited by the sim, thus avoiding unrealistic game results. So it seems.
This leads to tons of situations where the striker is alone before the goalie (sometimes even before the empty goal) - in real life you would jump from the sofa shouting out "yes, make it!", and in most times it really happens and you can turn the hope into jubilation. But here you have learned to stay calm, no shouting, no excitement, because you know the goal will only happen if the sim has decided that it fits into the probability calculations.
That creates an unrealistic feel while watching the game in 2D or 3D.
There is practically no midfield play. Every ball possession leads to either a direct shot on the goal or a misplaced back pass into the hands of the opponent, which is very ugly to watch.
The results may be realistic and may reflect the strengths of the teams. But this doesn't arise from realistic simulations of events, but because of retroactive concealment of the sims irregularities.
This is something that must be looked to if there should be any intention to re-write the sim.
