There are unfortunately quite a few issues with the game, but on the upside if they are corrected it would make the game so much more playable. Most have been covered from what I can see, but one I haven't seen (apologies if it is there) is the jerkiness of the graphics and audio on the switch. Clearly the game has not been adapted for it and is just a straight port. This means that the audio (everything from crowd sounds to commentary) is jerky, out of sync and, well, sounds like an old record with scratches on it. Likewise the graphics are just horrid, player skins are burnt to a crisp or have never seen the sunlight before. And to reinforce those that have been covered:
Marking is extremely hard to understand.
No training. This is a big one. For a game that has a huge amount of skills, there should be training drills to help players get used to the controls - which unless you bought a physical copy, they are also hard to understand as aside from the loading screens there are no instructions on what buttons to press. I don't want to go down the path of "FIFA has it...." but this is kind of a big one.
