I chose Night Fae because it was supposedly the best for hunters, plus for the aesthetic too. I didn’t choose for the story as I really didn’t have any idea what their storyline was. I figured I would find that out as I went through the campaign.
Later as I began to level alts, I chose Necrolord for my Orc hunter, both for story and aesthetic, and likewise Venthyr for my mage. The gear design seemed to really fit the class fantasy better.
I don’t care which one is best for each class anymore. I don’t raid/pvp, so I don’t think it really makes a difference for what I do.
