Most people don’t want to spend large amounts of time “getting good” and don’t enjoy getting matched up against players that absolutely destroy them, but instead prefer more casual games against other players with middling skills. The thing is though, even if highly competitive games include an unranked queue intended for casuals, it ends up being filled with smurfs[0] and the like looking to smash lower skilled players, which drains the fun from the game for those players. Thinking about it that way, it’d make perfect sense if the most popular PvP games would be those that are shunned by the highly competitive - a lack of “pro” players might be considered a feature rather than a bug.
