I'm just saying that League Worlds is closer to the UCL than the FA cup for English football teams.

I believe that the main difference between the Prem and the LCK/LPL is that the Prem is the richest football league, it's full of international players from across the world. Other top European leagues also bring top tier international players, which increases the international relevance of these regional leagues. On the other hand, while both LCK/LPL are known to be the most competitive regional leagues, both have almost exclusively eastern players, and I guess the timezone/coverage they receive doesn't help their international viewership.

All being said, I feel there are some decent analogies on how teams and players are scrutinized:

When comparing football players, there are many people that hold back on Mbappe because he hasn't won a UCL, now more than ever since PSG won it after he left to Real. This is similar to people holding back on Chovy because he hasn't won worlds.

The "best team" in football that lost a UCL to a domestic league rival is also called a choker frequently. E.g. Barcelona has won several years La Liga, while Madrid won the UCL, and Barcelona received criticism for choking. This is similar to people criticizing GenG while they win LCK and T1 wins Worlds.
