I returned to FFXI when I took a break from FFXIV last year, I stopped playing in a month.
Why? It takes 2 days to get a job 1-90 then you farm the same NMs over and over and over and over and OVER for pages for your AF3. Unless you want to run around solo/duoing old story content then it's all you can do. The End D:

I have faith in the direction FFXIV is going, if you are so dissatisfied I recommend you do what I did and take 5-10 months break from it and come back all fresh and new ^_^
