So far. I REALLY like what I'm able to do. I've shifted gears from how I played FFXI into how I play FFXIV... I plan to play casually and hardcore when I have lots of free time to myself.
My biggest annoyances were the patch downloads and early OB server response times. I would get ALL this speed the it would just time out but tonight I downloaded the patch and it was done with in about 6 minutes.
Also for those that are accustomed to using a keyboard to target:
Get a controller. It will only make playing the game and navigating so much easier. I only use the mouse ever so often to pick something.
The server lag has improved a lot in terms of response time. I'm sure that the connection status icon will be all greens once retail comes. One thing I know is that while we are playing they are already planning the retail patch that we'll all have to spend all night trying to download (I have collectors so...yeah...my computer will be busy

).
As far as game play goes: I'm still going to play. I'll more than likely stay a Elezen with the same name. I'm torn between a lot of jobs but I haven't decided on a main. I wanted to break away from magic cause that was my entire career on FFXI. I really like the point allotment system that lets me modify my attributes like the FFXI merit system (FYI - Piety is Magic ACC). One thing that I found interesting is that Mind controls my Max MP. I also like the elemental resistance options and how your job level and physical level kinda have to coincide to get the most out of them.
I really Really REALLY like the fishing system. I plan to do that and maybe weaver as a craft. I like trying a little bit of everything so I might be spending my first month just trying to decide what I want to do before going hardcore into other things.
