Bilingual People: What do the Korean & Chinese Communities think about 5v5 in general?

Ever since we swapped to 5v5, there has been a vocal group of people who claim it is awful and want it changed back. Personally I've never agreed with them, but I'm curious if that also exists in other regions?

Whether it is what content creators / influencers say, or just what common opinions are on forums, I have never heard anything from those regions about the whole player count debate.
