Due to an error introduced in a later update, the matchmaking system for Destiny 2's pvp pvp mode currently does not follow the game's usual skill-based formula. According to PvP design leader Derek Carroll, the error gives "much faster, but lower quality campaigns than normal." However, according to many Destiny 2 players, the bug results in a better PvP experience.
Generally, quickplay players are grouped according to their Crucible statistics and their connectivity. This gives fair play, but also slower and tougher games, which are not someone who comes to the quickplay mode for. Many players argue that since Destiny 2 has a competitive playlist dedicated to skill contests, it's all right for quickplay to be a little mess, as long as it's a fun mess.
Destiny forums and underreddit are crowded with posts and comments that commend Quickplay's random second wind and begs Bungie to leave matchmaking as it is. Destiny 2 YouTuber and PvP Specialist True Vanguard made a video that praised the current system and also drove a Twitter survey to measure society's opinion, which is an interesting piece of anecdotal evidence:
