The only gripe I have with FM at the moment is how overpowered the gegenpress playing style is, and it's been this way for around the past 5 years, If you use gegenpress on FM you will dominate/win many more games on FM than any other playing style.
I know it's been said that players will become more fatigued when using this style but I still don't think that's been implemented correctly, it should be that you need specific types of players with specific attributes to play the gegenpress as well as it plays.
I thought this would have been sorted by now, I know people will say it's not overpowered but if you go onto the tactics downloaded forum, most tactics are all press high, step up, press much more etc.
If you go and watch the YouTubers playing FM, the majority of them are using gegenpress, why? Because it's easy to win using it.
