The main thing I see a problem with right now is some of the XP bugs that happen, such as AOEing a group of mobs and not getting any XP for the ones that arent red to you.

Or the UI lag, yes its horrible, and makes crafting, trading, and vendoring items feel like shards of glass being dug into my fingernails. I pray that gets fixed before release

All the other problems most people have with this game, targetting, mouse, non-lag-based UI issues, are all fixed by using a USB controller.

Fact of the matter is, this game will be playable on the PS3. With that in mind, there's NO WAY they could make it feel perfect for the controller AND the keyboard, theres just no way. I know people who played FFXI for 1 day with keyboard, and completely gave it up for the same reasons listed as faults of FFXIV- all because FFXI/FFXIV need little message boxes on the back of the game box that say "Play with a USB controller or dont even bother"

Personally I love my USB controller, I sleep with it under my pillow at night, just like james bond does with his gun
