First, sorry for the Double Post, posting from a Phone has its limitations.
Lets assume and say Matchmaking would be "fixed" by queuing you alongside People of equal or near equal "skill", which WILL mean (judging on how squeenix always handles things) you fight aganist and with people from your Rank only OR within a rating score that works on a similar level.
The biggest Problem, such a thing would have, is the way how it limits itself and how it can be abused, allow me to elaborate further:
Lets say you are in Gold Rank with a Elo Score of 1500, the matchmaker only allows you to get queued with People +/- 250 to 500 Rating closest to you, prioritising the ones closest to you (since you want People who are closest to your level). Not only will you end up in a Match with always the sane People, it can also be easily abused to encourage Wintrading (like back in Feast, since low entry People from Unranked/Bronze will be discouraged to progress, since they only queue with "the worst") and History will only repeat itself at this point.
And then there is the matter of People using Alts for PvP. It is by no means a bad thing in itself, but a Alt character who'se only purpose is to sabotage matches in a legal way is a frightening hurdle to overcome, especially in a Elo Ranking based Matchmaker.
You only need to see the Feast Ranking from Season 18 from Chaos Datacenter and you will see what im talking about.
