I just restarted from scratch yesterday on Asura and from what I've seen from Sandy is that this server has a lot of people. It was like playing back when FFXI had just launched on the 360.
I also received help a few times without asking (which is nice), says a lot about the community of a server when people are willing to help out without being asked to.
I haven't had the chance to visit any areas other than the Sandy starting areas but I'm hoping the rest of the world is as full and nice.
I quit about 4 years ago and tried to restart on my old server Alexander about a year ago, but it was so empty that I had to quit.
I thought what I'd do was, I'd pretend I was one of those deaf-mutes. That way I wouldn't have to have any goddam stupid useless conversations with anybody. If anybody wanted to tell me something they'd have to write it on a piece of paper and shove it over to me. They'd get bored as hell doing that after a while, and then I'd be through with having conversations for the rest of my life. -Catcher in the Rye
