Anyone who plays Online Ranked and looks for higher ranked people isn't going to play Player Matches. Player Matches lack win percentage (a numerical value for so-called "expertise"), and often imply successive matches, where the normal player wants to simply beat a particular opponent once and carve that notch into their shillelagh, never to allow a rematch (that day, anyway).
The person who wants to actually improve their character repertoire and matchup abilities will, eventually, migrate to player matches, either by themselves or through friends, and start building a network of people to play against. Anyone who creates a thread like this is not seeking to move to Player Matches, sadly.
