Due to a bug introduced in a recent update, the matchmaking system for Destiny 2's quickplay PvP mode is currently not following the game's usual skill-based formula. According to PvP design lead Derek Carroll, the bug "results in much faster—but lower-quality—matches than normal." But according to many Destiny 2 players, the bug results in a better PvP experience.

Ordinarily, quickplay players are grouped according to their Crucible stats and their connection strength. This makes for fairer games, but also slower and tougher games, which isn't what some people come to quickplay mode for. Many players argue that since Destiny 2 has a competitive playlist dedicated to down-to-the-wire contests of skill, it's perfectly OK for quickplay to be a bit of a mess as long as it's a fun mess.
