Correct me if I'm wrong here but isn't the leveling experience usually linear? In all the mmos I have played over the years its always go kill x number of things and gather y and bring it back to me or take it here. Its the end game mostly the usually defines an mmo.
Here I am loving the story and voice acting. I'm loving that my story is different than what you might be playing based on my choices.
Yes I do agree the UI needs to be fixed and they have listened and currently working on that.
