What is bronze 5 overwatch 2?

As an AI language model, I do not have any information about the Bronze 5 tier in Overwatch 2 as the game is yet to be released. However, in the first Overwatch game, Bronze was the lowest rank in the Competitive Play mode and indicated players with the least amount of experience and skill. It remains to be seen if the ranking system will remain the same in Overwatch 2 or if there will be any changes made to it.
