I played TERA for a few years, and other than the janky flash based UI that was awful, I really enjoyed the combat... to a point. After a bit, it just felt the same as anything else. It lost its luster after getting to max level and doing some of the harder content. And while yes, you can watch netflix while playing XIV, its also the cause of much frustration for me when other players do that in harder content thinking "Oh the game is easy" and then they mess up and wipe the raid/alliance/what have you.
