The first team I heard of using platinum (Fury Platinum) was not to designate the level of talent, but to differentiate itself from the organization that they broke away from (TN FURY). Obviously, the logo was changed, but I assume they wanted to hold on to some of the prestige of the original Organization’s name. I’ve started to see more teams using platinum as a designation of talent like gold, elite, etc. I wonder if they are just copying an org name and have no idea why they use it.
