Personally, I hope to see:
-Custom color sliders for the eyes, hair, and skin of our characters - or perhaps a custom color wheel, like what you see in graphics-editing programs, instead of being limited to preset color options.
-Custom facial sliders, making it possible to change the expression of a character's face while also being able to individually change eye size + eye shape, nose size + shape, eyebrow width, size + shape, facial shape, and mouth size, width, and shape, instead of being limited to preset facial options.
-Being able to mix and match the ears and tail on the Muris and Turga races, along with more options for selection on the ears and tail of both races, and possibly the option to only have one ear, and/or no tail on both races.
-A wide variety of battle classes, like a bard/musician-type class, a summoning class, and perhaps a martial-arts type class in addition to the classes already in the game.
Of course, I can dream. *-*
