S-Tier events are events with the best teams in the world and have significant meaning. Crowds are part of it sure, but they are not the main reason events would be considered S-Tier. S-Tier events in Valorant are Lock In, Masters, and Champions as they are directly part of the Valorant Champions Tour and contribute directly to a team's placing within the VCT. A third-party event hosted by Mr. Beast, Ludwig, or Tarik, would not be considered S-Tier whether or not the have a crowd since they do not directly contribute to the VCT. It would only be at most an A-Tier event. Riot supports 3rd-party events as we are seeing this offseason but they absolutely could do better.
