Yeah I got into a long discussion about this in game. It is a tough question that obviously has no right or wrong answer.
I think I'm going to try to play all 8 class stories first. From that figure out which I enjoyed most. Not so much the story but the actual game play and then start with that class moving forward.
I will be having a surgery soon that will have me at home for about 6 weeks,.... so I'll have a lot of free time to play!
