I left a month or so ago. Had reached VR2 and felt a bit tired. I played Wildstar a bit, but quickly tired of the graphics, gazillions of pointless quests and walls of text that accompanied quest givers. It's fun in other respects, but ESO just feels more "grown up". All the things I liked about ESO when I originally played still rang true.
I started a new character in a new alliance, and it feels like I'm playing for the first time - which is great. And, despite all the whining and moaning on this forum - the game feels a lot smoother to me; it certainly feels like it's improved.
So 2 thumbs up for me right now - hopefully it lasts this time.
