They did say that the Japanese people are more competent in the game (our Savage is their Hard mode) and therefore, they don't complain that much. They are also more towards communication and group play rather than us, individualism and solo-plays.

So, it makes sense that their threads are more towards fun things rather than our complain threads to make this one class OP in regards to it requiring 10 seconds more to complete this dungeon than this other OP class.

Mentality. Also, we're not afraid of voicing our opinions and stand in the pool of shame but in their culture, shame is a lot more like insults and should be taken seriously. Just my two cents on the topic.
