No heartburn, just explaining the issue. Invalid squads with just 1 member are listed in the rankings excepting the first 25 positions. A person in a valid squad, tracking their squad ranking, who wants to compare with other valid squads, will not see an accurate ranking. They would have to check every squad above them for number of members to see if their ranking actually moved up, down or stayed the same.
Maybe I'm missing the reason why some squads are marked invalid in the top 25 but should be able to see their rank when they rank lower? If you don't have anyone else in your squad you can still see your individual ranking and that's a more appropriate metric for an individual.
I agree it's not a big deal. The issue is simply that single player squads skew the squad rankings and there are players who care about this.
