Why not adjust Miqo'te ear size? Maybe they're doing that instead of making another animal-based race (bunny-ears?) I really don't see it as being hair length. I do agree tail length is a possibility.
Now the races do have their own starter undergarments, but maybe the new starter gear will be multi-purpose similar to FFXI?
Bust size isn't too important to me. For Elezen, it did change slightly based on Elezen race and body type, you just couldn't manually adjust it.
I think its a good idea that I need to visit an area to view a map. Its makes exploring more fun in my opinion.
Delivery NPCs... At this point in the lore, it seems odd to have moogles delivering items where they sing in the forest of Gridania, or summon their tyrant king to fight us. However, the 2.0 storyline will be different and that will probably fit the lore there just fine.
All in all, I'm looking forward to the changes.
