1.Yes, but I'm also having concerns of its future.
I'm still having fun playing this game with friends and the nice randoms I just meet on my server. There's also alot of things I have not done yet.

2. Since 2.3 I believe. I was stupid enough to decline a friend's request for me to join during the beta, now I play the game more than he does.

3. Not particularly. Wasn't a fan of MMOs but I revisited an MMO from my childhood for the nostalgia, but it shut down a while after, sadly. After that I tried out FFXIV.
