Interestingly somewhat recently I transferred my alt from Adamantoise to Sargatanas, and wow the difference was huge, maybe i just ran into the wrong people, but everyone i ran into on Sarg (mostly pfs for doing final coil) were total douchebags compared to Adamantoise. So if you're looking for a server for endgame reasons, Addy has a good end game crowd that isn't completely full of jerks. (Of course you'll see them from time to time) but on Sarg it was epidemic.

Hope you find your new home! And if you transfer to Adamantoise feel free to hit me up.
