This was the exact same in FFXI, whenever i partied with jp players they were usually more polite and MORE forgiving, They also did that same thing, those magic words nice to meet you and bowed on every invite.

I sometimes wish i could learn JP cause they are far less stressful to deal with then NA players, now don't get me wrong there are some A-Hole jps out there, racist and what not. but they are few.

I really should not be in a community where i have to fear making a mistake due to backlash or getting angry at random, common mistakes. like recent i saw a tank blow up on a healer when it was entirely the tanks fault he died due to basic stupidty (long story)
