Aha but if you win the title then you have a extra of 50 points, and the inactive 6th can mean don't win, be second and sum +25 and not + 50, here were I wanna go.
Sack the inactive that often is a sure defeat and force a 5 vs 5 with full actives give more stability and chances to win the +50 extra.
"Despite all, all depend of the activity."
Of course I am talking, of 1 case, one specific scenario/situation, in what have 5 is better than 6. The question was if "existed a case in what play with 5 is better than with 6". And this is the case, if there's a inactive or maybe 2, if one have 6 actives, of course, is better than 5 as they can manage the matches if exist activity.
So these associations that see that a member disappeared, win more sacking him than having him.
