This might need to go in the "Returning Players" section, but meh.
Inflation
SE has recently banned lots of gilsellers and taken lots of gil out of the economy. At least on Caitsith, the prices are on the downswing (mostly). The economy is pretty good in my opinion. Prices are higher than I would like, but so are the farmable items.
Japanese Nationalism
Of course there are some Japanese players with "{English}{No thanks.}" and "JP ONRY," but honestly I've seen a lot less of those comments than in the past. We're pretty much on equal footing now, at least moreso than two years ago. Then, NAs didn't have many Lv75 jobs... now we have NAs with Maat's Cap. So there you go.
WHM Party Seeking
I think the longest I've seeked (at WHM62) was fifteen minutes. I'm not sure how it is for Lv70+, but I'm sure the demand is still high.
Expansion: ToAU
This is an entirely new expansion with no annoying Promyvions to do.

Seriously, Aht Urhgan is pretty awesome. Only 7 or so missions have been unlocked (mostly cutscenes), but this expansion is
much better than CoP. By far.
Have things changed?
Yes and no. There are still gilsellers; there are still JP ONRY players; there are still bad parties and n00bs. But it has gotten better.
