Warrior looks like a Beastmaster to me :o
Even though he has fur lined boots/gloves and horns, I don't get that impression. Maybe if there was more fur, less plate and the horns were actual horns instead of metal.
Quick, everyone bombard the forums with magitek flying gunship mount thingies from the intro cutscene! We need Magitek flying gunship pvp!
In all seriousness, if they go into personal flying mounts (i dunno how i feel about that yet), those things would be kinda cool...
As for the live letter, Everything they showed looks really cool, even though I got owned on the whole Archer/Bard thing.
I missed the discussion about the maps, but based on his hints I'm thinking that a full world redesign is coming as part of the imminent danger in Eorzea.
Flying mounts couldn't exist in a world with invisible walls, inaccessible areas and zone lines to the degree that this one has, and will have more of in the future. Not to mention flying mounts really create a whole slew of problems.
I wouldn't mind free company airships though, and hope to god they plan to implement them eventually. But mostly for quick travel to key locations, and perhaps use in certain boss battles and special company leves. Free flying would be impossible really. Unfortunately.
