my expanded roster is knocked down to "30" too. I have no problems deviating from reality
if a team has more than 5 mlb-quality guys at AAA, welll, too bad, lol. the ai too often adds prospects to the 40-man before they need to. the expanded roster size is what it stays bloated at over offseason, so it helps with this too, i think.
that's how i see it, too. the minors are for development. I care not for anything else. i even have the statistical detail set to the lowest setting for those leagues. anything i can do to speed up the simulation in that area, i do -- without impeding development.
i.e. rules can be detrimental if too strict. after rookie, it needs to really open up as far as where people go as to not restrict flow or cause a bottleneck.
once in a while i recalc the modifiers, but in general, i ignore nearly all aspects of those leagues. i do micromanage promotions/demotions, but that's just to provide a winning environment.
