Being one of the first NA high lvl players back when FFXI released, I had the privilege of grouping with many jp players, as a majority of the people my level at the time were..jp players.

It went a little something like this:

Me: "Looking for exp group, DPS"

Get invite to group.

Group: <something in japanese>

Me: "Hello all!"

Group: "JP ONLY" followed by an immediate kick.

The only thing more annoying than the whiners of the NA community? The one's who worship jp culture and just have to boast about how their JP servers are so much better, even though a majority of the time they're simply looking through rose colored glasses.

90% of my experience with the Duty Finder on an NA server has been positive, I only see spammers in the market zones for the most part. That must mean everyone shares my experience, therefore NA servers are superior! Right?!

/yawn, They're people, just like NA, get over it.
