And leads to "toxic" behavior. If you behaved poorly in a dedicated server environment you could be banned from multiple servers in one go as each clan might host multiple servers. Eventually all that would be left for those people would be a handful of lawless servers, enough threat of punishment to deter shitty behavior, not enough of an impetus to buy a new cd key and reimpose yourself on others. In practice, most people just behaved better.

It is bizarre to see riot and blizzard run around in circles trying to combat their toxicity problem... its your meat grinder matchmaking system.

As it turns out, matching people against those who are exactly their skill level isn't what you want to do.
