Overall, I really like the new update and I'm very excited to be playing this game again.

Auto attack is the best improvement by far. Because of it I actually enjoy battles. I find myself using more abilities and strategy since I'm not constantly racing back and forth between my basic attack and my other abilities. It just feels like I'm not longer fighting against the interface to play.
Quests giving SP now is great. There's finally a reason to take these quests and explore the world and lore surrounding them. I find them rather addicting!
The public dungeons (or at least the one I've done) are a lot of fun and present a nice sense of purpose and comradeship for groups!

The only changes I'm not too sure about are the huge MP cost for spells and reduced SP rewards. I don't like that CON is being shoehorned into healing. What is the point of having a class with both recovery and attack magic if they're going to be forced into one or the other. Overall, I don't think it's as bad as players are saying, but it does need a little tweaking.

FFXIV is finally starting to look like the game I thought it was going to be when I bought it. With chocobos and airships coming next, all I need is Mog houses and I'll be set!
