BC Wels, in your league, started in s18. By season 20, he was a PO team in II after having spent a full season in III so making less than what you are making now. Currently, he is 10-7 with a 100k roster which is probably still under the salary floor. So you could have a more interesting season, you are chosing power-gaming, the game is not forcing you.
in Bundesliga :
BB Chicago Bulls, the leader in conf 2 started in s12 and has reached the PO every season since s18.
Lightning Ravens, 2nd in conf 1 started in s13 and was in the finals last season.
Somehow, they have caught up. Quick. Quicker than that would be very quick.
Not sure many top teams have savings, this has changed with the stop put to the rising market.
Out of your 4 players, I don't know who you are training for the future of your franchise. Who is the 3rd slot ? Is it the 24 yo with a salary of 3.7k or the 27 yo with a salary of 3k ?
You are not training Bacardi for your franchise. Your will trade him for more cash.
Only with Kastner you are building something.
You are free to play this way but then it's normal that you get bored.
If you were in a bigger country, after 1.5 season, you would be in the same situation, in a bot league, winning every game or at the first competitive level getting beatings after beatings. Only it could last longer.
