I like being able to call a chocobo anywhere in the field without having to recharge a stupid whistle.
I like seeing mob levels without having to /check every mob to see if it's TW or super IT++++
I like not having to drill down through a menu selection to pick everything.
I like not having to eat scrolls to learn a spell like in XI.
I like instantaneous teleportation, and offering that same teleportation to others in your party.
I like being able to actually see earrings on my character (of course her hairstyle mostly gets in the way, but still)
I like silky smooth 60FPS goodness as opposed to FFXI's sluggish 30FPS cap
