Ragnarok used to be bad, but it's really changed.
At one point I often saw 6 archers/bards trading to one person at the Ul'Dah crystal, all in same gear with head-to-keyboard names and a lot of tells.
Now, I get at most 2 tells a week, sometimes no tells for weeks.

No idea why they left ragnarok but are enmass on other servers, perhaps because they didn't sell any gil there?
