There isn't a number of teams or method of selection in which everyone will be satisfied and there isn't a rational argument on why it isn't fair. I said that years ago when they first started the selecting top two teams ranked, said it again before expansion to four teams, said it again past few years before this expansion. It is imperfect and always will be. Quit fooling around thinking it can be fair to everyone.
I find this year to be exciting and the regular season mattered for more teams longer. It exceeded my expectations. But at least one and possibly up to three teams will feel screwed next week. No way around it. My advice, don't lose games you should win late in the season.
