It's really good, but I mostly liked the Bitterblack Isle area that Dark Arisen added, far more than the main game story and overworld.

You'll want to level up all the disciplines to mix and match passive abilities, but definitely try to main any of the daggers + bow classes, they're by far the most fun and varied, IMO. Strider and (later on, when you get a decent magic bow) Magick Archer were my favorites, but Assassin and Ranger are great, too.
