I could probably count on one hand the number of times I've partied with Japanese players in V1 who weren't in my LS (we had a couple). I'd much rather have a larger playerbase online during my play time than open up that possibility. But I suppose it's different in Europe. JP players are usually asleep during our prime time while NA players are at work. Of course you get the odd one who doesn't work and plays 24/7 but I'd rather not have to factor them into my plans.
