suggestion for battlegrounds matchmaking system

[randompandawowplayer]

almost every bg is like this, heavily unbalanced, one team has many full gear players and the other has many x100 realm or griveous gear players, there is no balance in most games (not all), we need a new matchmaking system that takes into consideration each player ilvl and in-game time and spread them out evenly on each team

and maybe even reduce the premade groups to 2 players max, because a premade of 3 full gear good players is already almost half of a 10man's team
