If Oasis stopped releasing stronger ninja than the previous, what would happen to the game after 3 months, 6 months, or a year?

So Obito 10T BT would be the strongest with Naruto being nerfed. You want that to be the state of the game forever?

Online RPGs only release stronger features and characters, never weaker (increase in caps, maps and monsters). Why would this game be any different?
