It is much better and I feel the majority of the moans are because everyone is accustomed to the old, 'buy 11 players, win the league' mentality and that is not through the fault of the user, it's just the way the game was able to be manipulated in previous versions.
Team-talks are much more difficult and you do have to garner the support of you're players before they'll respond to you. (something as simple as selecting sunday league footballer for past experience when choosing a premier league club has a negative affect as it would IRL).
The match engine does not have as many bugs as posts within this forum would have you believe. I know people download tactics but it simply won't work on this version, you need to create 3 solid tactics for you're own team and individual players needs. Downloading goalsgalore.tac isn't going to get Grimsby Town into the Premier League. Each match needs preparation and tactics inevitably need adapting to counter specific threats, for example I play zonal marking and rarely close down outside my own area unless an opposition player warrants that need.
The opposing team report is invaluable, many times I've adapted my Newcastle team (particularly away from home) to counter the opposition. The latest being Everton at Goodison Park where I moved Santon to the right and man mark and press Baines to counter the fact he was their leading assist player. It worked and we won 3 v 1.
Not too sure on the weather aspect, haven't reached the winter months but from what I read pre-release it will have an affect on teams playing a shorter passing game like Barca, Chelsea but probably favour long ball teams like Stoke.
My final point is that the training and match preparation is essential and the training interface is far more user-friendly and intuitive than previous versions.
My final, final point is that the Director of Football, Head of Youth Development and Chief Scout roles are brilliant and with the right staff you can delegate particular roles from buying and selling players (a la Daniel Levy at Spurs) to allowing your Chief Scout to look after the clubs scouting network and allow him to send the scouts around the world. Even the coaches have varying qualifications and can be sent on courses to get their B and A licences.
Overall, best version on FM by far and the most demanding in terms of immersion and detail.
Have fun
