It definitely has some jank and is by no means flawless, but it offers the second best storytelling in an MMO next to SWTOR, has an interesting setup for combat and special abilities and a really great setting. Sadly the first three areas you start are by far the best setting-wise, but the other are pretty good to.
Still it is has been an all around solid experience for me because its overall concept just clicks with me. Some parts are brilliant, most are fun, some are WTF, but it's been incredibly satisfying to me.
One of it's best feature, though, is the ability to redo almost every mission there is in the game. If you liked a certain mission or chain of missions or one particular area you can go back and do them over and over (after a cooldown). No need to make a new character.

Bugs from launch day still exist. So it's a finite endeavor and quirky (at times) endeavor.
