You enter the matchmaking options. You select your desired game mode(s), you select the max ping and finally the server size (24 players, 32 players etc). You press “Search”. You join a server with players of equal skill*.
This method does require a reasonably large player base to work, but I’m positive that new players (and old players that quit early) would find their playexperience far more enjoyable when faced with reasonably equal odds.
*PS: How to properly judge someones skill level can always be discussed later. Bronze player, silver player, gold player? Doesn’t have to be so complicated.
