I was involved in an awesome & friendly E-Mail exchange with AXIS Football's president about AXIS Football Game & Simulation Football League, which involved a lot of E-Mails about Tier feature. If you do not know, if you do know, I am sorry, but to be fair- Tier is when Sports Assications &/or Leagues, at the same sports level, are all connected, so that at the end, the teams-franchises with best & worse records either automatically or played additional games to move up/promotion or down/relegation to higher or lower associations &/or leagues. Here is the url to more information on how The English Professional Soccer Leagues does Tier-

Before the exchanges, I had known & understood about Tier & thought it was not necessary, of course, afterwards I now know & understand a lot more, having been refered to Internet search on England's professional soccer version of Tier, & think it is needed to keep teams-franchises competitive & not just there for making greater wealths & powers.
