Something i think would be healthy for the game is the ability for players to set up custom tournaments. More specifically the bracket style. As an example would a popular guild or streamer create a for all to see. It would be visible on a board of sorts. You could go in and look at each participant in the pool. Transparancy is key.
Of course this could be done 1vs1 matches by the players in a way but the effort would stiple the content created that would create a ecosystem of its own. Also the transparacy of an ingame system minimizes rigging or cheating with who participates against who since there will always be a bias in guilds, dont know about streamers.
Use the same system for naming these as for nodes. Exceptions for popular brands. They earned it.
Some examples down below:
