Well don't make a decision just based off me. Others in Zam will respond and can give you more detailed feedback.
I think the graphics and art will remain the same. There is a detailed road map as to the things that will be implemented by or before 2.0 floating around the boards somewhere and I think on the official forums.
Many are paying to play in its current state and are happy with it, many are not. I was an XI vet, and tbh, if I weren't so busy with rl at the moment I would be back at XI.
XI had a certain feel to it which XIV has not been able to provide in its current state.
The MS is soloable, but IMO convoluted and broken up to where it is hard to follow. I haven't been following the lore, maybe someone else can comment on that. Solo/Duo content is heavily lacking if that is a route you are thinking of pursuing. Crafting is pain steakingly boring. Gathering hasn't had many tweaks done to it in a while, and is in need of more quests, leves, something to make it more fun. Battling solo doing repetitive leve quests makes a casual player bored and at the same time annoyed cause getting parties is rough below 40, unless you can get someone to p level you, which takes the fun out of the journey and not knowing your class well if you haven't played before.
I am sure I could go on, but from a frustrated players perspective, you get the picture.
