I really wanted XIV to be a good game, have been hovering at a safe distance ever since I played the abysmal beta waiting for it to get better. It looks playable now which is a little tempting, but I really want to hold out for 2.0 before joining a game that is likely to be hit with a meteor and have all its mechanics and content reset.
Thankfully I'm busy as hell this month so hopefully the urge to try it will go away.
I think folks are misunderstanding some parts of 2.0. Content is all new, but the mechanics that were revamped are here to stay. At least that's how Yoshi_p put it. If anything 2.0 is hugely cosmetic and UI.
Edit: actually I recall him saying the mechanics here are parts of 2.0
