I agree, WJC is only for under 19, however, its technically still classified as a tier one tournament for ppl under 19. But I do agree that since its only for ppl under 19, its not considered as prestigious as the other tournaments. However, on the senior level and for individual events, then the only tier one tournaments are OG and WC right? I understand if some ppl go by the terms like majors, SS, etc instead. But there are also ppl out there who classify tournament by tiers, thus it is why I'm asking the question.
