XIV is absolutely a welcomed upgrade from XI. Most MMOs are unplayable at launch and sometimes never get better. XIV launched with very few if any bugs and my only complaint is Lag. Which is to be expected. It hasn't even fully released yet.
Those who are asking is it bad why is it bad blah blah. If you are looking for a reason to not like it you will find one. But if you enjoyed XI and want more of that fun without the problems of XI then XIV is your MMO. It is beautiful, fun, intelligently made and well polished.
Play the game for yourself before you listen to ANYONE else. Ask a friend for their 30 day pass. I will gladly give mine out to someone who needs it when the 30th comes by.
Also, Besaid seems to be a good place for anyone just joining if you are looking for friendly english speaking individuals with a fair mix of NA/JP/EU players.
Those my 2 cents. If you don't like them well there are no refunds.
