Make zones smaller and add LOTS of variety. I want a desert, a volcano, ice caves, castles, catacombs, etc.... What we have now is just bad. I don't really even care if you need to go back to FFXI zone sizes and make me load every time I switch to a different area. It is a necessary sacrifice.
Class Distinction - Every class feels the same. I can hop on a Gladiator and feel like i'm playing a Lancer. There's just no feel to it. It doesn't feel different in the way XI did.
Crafting - I know you wanted to make a player driven economy but there is seriously too much of an emphasis on it. Everything you do in this game requires a crafter for some reason or another, even the holiday events (which is next). Please tone it down a little with the heavy crafting emphasis.
Battle System - To put it simply - it's extremely boring. I don't really feel like sitting around mashing the X, A, or 1 key over and over. There is no strategy it is simply button mashing. Monsters are either really over powered or extremely easy. The poor animations and the mashing just makes me want to vomit. I am on the side that is in favor of the Auto-Attack (which I know is controversial).
