It is fair to review an MMO after release, after three months and after 6 months. What are you people smoking?
XIV wasn't a good game at the time of release. It isn't a good game now. It may be a good game in 6 months or not. All we can do is wait or not give a crap (like the most). Reasons for the slow dev cycle are simple, and clear. Not excusable, but all you can do is deal with it or move on.
