[Impossible to rejoin National team after being fired once]

It does happen in real life and it should be possible, not impossible.
If you are by far the best candidate you should be able to get the job again.
Btw, it's a game, I wan't to manage my own country and can't. Not even 5 CL wins later. It's a bug.

I don't think it matters if it ever happened yes or no. It's about the possibility not being there.
Also, if you consider winning the World Cup with the NL, you would not get fired if you play an "ok tournament" with a bad squad 2 years later.

And if you did, 10 years later the world can look completely different. So the possibility should be there, I feel it's not possible in FM.

Since I can't modify my post I'll add another thing that hasn't been improved in years (applies to the AI).
They don't seem to rotate there squads enough at all. If I play a CL match and a small opponent in the weekend I play a B-team or at least spare some of my key players.
Then I play the AI team in the CL semi-final and they are tired after 45mins because they used the same squad in the weekend.

Not realistic, not ever improved.

So I play since pretty much the 90's when it was still called Championship manager and some things have hardly ever improved over the years.
I don't play short saves and don't do big clubs, I start in a lower league. I play long saves (20+ years).

- AI Squad building. Over time the AI can't make the right decisions and all competition seems to dissapear.
Winning Champions League Final with 5-0 is no fun.
Also watching some of the transfers going on, it's just very stupid. 
I also feel that the overal quality of all the teams seem to decrease over time.
Anyway, some hard work needed here.in this area, for many years now.

- International Management feels shallow. 
    When a team loses some of there key players, or the next generation is poor compared to previous years the board still expects you to reach the same goals.
    There is also no discussion in this, expectations vs reality.
    Also if the goal is to reach the semi final and you dominate every game, win by big margins and reach the quarter. In the quarter you lose very unlucky, although also dominated the match, you still get fired because you did'nt reach the goal.
    This is also unrealistic and there should be talks before ending contract.
    Also it seems impossible to ever return to a job (even 10 years later) if you got fired once before. No matter how many titles you have won since and still hold best internation records with the corresponding country. They always pick someone else, even with poor records.

- Social media in game.
    Use ChatGPT or something similar for this to make it much more dynamic and real instead of reading the same messages over and over again.

- UI obviously needed to improve years ago, finally we are going to see something completely new with FM25. Looking forward to it.
Hopefully the GUI will look and feel more like a game than before.

What did improve a lot is the match engine. I hope they kept it somehow in Unity, because for this was the strongest point of the game the last years.
I've seen goals and incidents that looked like real football.

Maybe people can add stuff I forgot
 

[Impossible to rejoin National team after being fired once]

So I noticed pretty much in all FM's going back from 24 to 19 that getting back the job of international coach for a country you did before is impossible.
I was fired eventually in all cases after one poor tournament.
For example with Netherlands, I won Nations League, World Cup and eventually the squad lacked any real quality and lost early in Euro and got fired.
Still have the best win/loss ratio. Have won many titles with my club since, including champions league.

However, 10 in game years later if I try to get the job it never works, they always choose someone else.
I think this could be a bug?

I always play long saves. I like to start with a small team and then work my way up. The first couple of seasons are always a challenge. 
Eventually you end up with a 4.5/5 star team and you will win the Premier League and CL every single year, with the occasional exception in CL semi/final.
The game gets boring and repetitive, also because of the complete lack of immersion and repeating press conferences. 
I always check what the competitive teams do and the AI is just terrible, most teams had a btter squad when the game started.
The only way to find a new challenge is to move away from the club.

If the AI can't keep up, or it would be to harsh for our PC's then I suggest to use "balancing scripts".
In other words, if my team has eleven 5 star individuals, then maybe it's time to spawn some awesome regens to other clubs and specifically the competitors.
Make sure they hold on to them and then after a couple of seasons the challenge might return.
