You are the first person I've ever seen to suggest that the difference between a 2200 and 2300 player is less than a 700 and 800 btw; I actually misread your first post because I thought it was the classic post that everyone below 1000 is the same skill level.
Also, these suggestions would make you match with an even larger difference than what currently exists. It would basically double the search range for 1500 players. Or are you suggesting that teammates can only be within these rating limits? In which case I don't understand these rating limit brackets.
Why would you have no skill limit, followed by a 500 skill limit, followed by an 800 one? That doesn't even make any logical sense. It can't be based on playerbase size because the group with 70% of the players (<1000) has no limit, but it also can't be based on any sort of rationale about skill level being larger or lower based on your place on the rating spectrum.
