There are different formulas that can resolve the current drama... What you are suggesting about FAs % power Draw is in the line of what Ive mentioned too, just if a team starts the season at 100% avq, play in +1 level, if 120%+ +2 and if 140%+ +3 levels. Then an activity/success factor could be added so to give opportunities time to time to those Who didnt win trophies for a while...
As always,va complex topic.
