To be fair, we had a huge issue in ffxi with jp players taking na players with them on boss runs and then booting them before loot would drop, which is one of the reasons you cannot kick someone when something is in the loot pool here. NA players didn't have that much of an issue with since reputations spread quickly among the NA playerbase. One guy on our server couldn't even get people to lvl with him his rep was so bad. Not to mention the "English? No thanks" problems.
So stating that JP players are just overall better is not really that true. people everywhere are jerks, it just depends on who you encounter and your own bias that allows you to see one as being superior to the other.
