Tops: It has a lot of depth that at first glance would not be obvious. The fact that not being part of any realm (rogue) is harder to maintain, and not desired, than joining some realm also makes this pretty easy to get with some other people and start fighting. It's not like those games where guilds/clans/whatevers only go for people who have played 24/7 for 10 years straight and have stuff like damage calculation tables memorized and experience rates optimized.
Flops: Well, being in perpetual beta...there are bugs. Have I mentioned the times when on one character (Ramuh) I somehow ended up in limbo twice? Seriously, one time I was even in no region and couldn't do anything but message people and check on information. That was interesting.
