Matchmaking is absolutely necessary in any player vs. player game. Even more so in a game mode like battle royale that is very unforgiving. The only potential drawback is the wait time, because if you implement matchmaking there will absolutely be a wait. That's something I'm perfectly fine with, as long as it doesn't start going beyond a couple minutes. Even by matching players of a similar level you already reduce the amount of elitists in the lobby. Of course there is going to be smurfs, but that's inevitable and not as big a problem as people like to make it out.
