I think a fair amount of time to give is until 8.0, personally. Which is probably what I will do, as much as I dislike the story in this expansion and lack of any meaningful change, they still have some patches to cook on.

If the story continues to be alá 4 kids, very juvenile with minimal QoL and 8.0 announcements contain the same old package, it might be time to hang the hat until they do fix the game to be more interesting outside of hanging out or some other MMO manages to offer the same type of experience but with a better engine that can work on things more fluently.

No hats for Viera and Hrotgar for how many years now? I don't even play Viera or Hroth and it makes me upset for them.
