I think in a basketball manager game the MANAGING and COACHING of the team should be the most important aspect. In a real game you can make adjustments and talk to your players and change tactics DURING the game. I absolutely agree that it is not fair to people who work and have important things to do to expect them stand in front of the monitor during the game.
but you won't make such adjustments, there the adjustment the engine make are much more realisitc, you start with a gameplan and during the game you concentrate more and more on the working plays. So if you play run and gun against a 1-3-1 Zone, you start to search the man under the basket more ... Not you are playing first quarter LI, against 3-2 and switching to Run and Gun - thats no adjustment and such behaviour would avoid adjustment from the system to the opposing game.
Also if you scout your opponent and know he play one quarter LI, one run and Gun, one Motion and one Base - how you could plan your defense on it? I could tell you how i would defend the single offense but to find the right quarter would be pure gambling for thsi i like it more like today where undecided player have to play a "normal" offense focus over a game.
What do you mean with epileptics?
totally randoms switched in gameplay
what do you mean with lineup page will be overloaded?
For tactics offensily, four tactics defensiv and to make it a bit reasonable four lineup with 15 spots - for me thats alot.
Therefore I think a variation of tactics per quarter before the game should be possible. You're not obliged to make use of it.
If my opponent switched tactics i had to react, so could you please make constructiv input ;)
