I might be not sure but I have admit the possibility. I don't know if I'm looking for something that, as you said, doesn't matter much anymore.
The thing is that with the same save I'm managing two very different teams: FC Porto, main contender in the portuguese league, and Boavista FC at the III division (currently II division after being champions). I'm at the 3rd season, three with FC Porto and two with Boavista, and with FC Porto we've won 2 titles, 3 supercups, 1 cup and 1 league cup and reach in both seasons the semi-finals of Champions League. With Boavista I've found quite easy to win the III Division Title and although the press forecasted a 19th place (out of 22) for the II Division, we are currently at the 1st place and still competing both in cup and league cup. Two different teams, two different tactics and what I think I can call two stories of success.
So, considering this how can I post my frustration ? I guess my deepest frustration regarding this year edition of FM is the step that was made regarding the new tactical system. SI have conditioned us all to play into their own logic of football, introducing a very rigid system that only facilitates success if you play by their logic... and it's a british game, so it's a british logic. This is very frustrating and also very wrong, mainly because the game allow us to manage a team in a great variety of countries and each one, in each league the logic / idea / style / philosophy of football is different, so it's obvious that the game should allow us (as it did in previous editions) to set our own logic. Possession based style is highly damage in this edition: not that it's a problem to have possession (like 65-70% or more) but either you have this high possession or you have results. Wanting both is kind of an impossible mission.
Then we have the specifics:
a) it seems SI looked into the main European leagues and concluded that even the top teams end the championship with an average of 1 goal against / match (a kind of 38 matches played / 38-45 goals against). No matter what, your top team will have this average or close to. Completly irrational because 1) why can't I have the tactical and strategical freedom to achieve a lower average ? 2) most European leagues are not as competitive as the top leagues (portuguese league is not) so it's rather common to see top teams at minor competitive leagues to achieve lower averages... for SI it is not;
b) FM13 had a few on / off instructions: if, for instance, I would need the all structure of a DLP but without the hold the ball instruction that was just fine, I would just switch off the instruction. Now I can't! I have to choose a completly different role in order for that player doesn't hold the ball... and a different role is a different structure, with higher or lower mentality, with higher or lower CF and it will have deep implications in my style of playing.
Like I said, I have no problems with winning and with two different teams, so I can't say my frustration comes from lack of results... but my frustration has a lot to do with SI defrauding my expectations because I can win but only in SI terms and logic. And football has nothing to do with logic!!!
Finally, by other frustration is to look into a game that has evolved a lot, that in spite of lots of bugs still makes me vibrate during matches but still lacks things that are basics:
a) Shout instructions to motivate players simply doesn't exist: if my player is complacent, I can't do nothing;
b) Defending throw-ins set piece instructions doesn't exist
I guess at least these two should be very simple to introduce, although I would consider that by now it should be a reality to set tactical instructions when your team have and doesn't have the ball.
