Repeating what's been said mostly but I'm actually comfortable where I am - even as a Midlander I only changed my hair a grand total of once (and that was after the hair from the Ivalice raids came out, I'd been looking for a ponytail I liked on him for ages). But I do agree that in the future when more styles come out that I do object to needing a Fantasia to change one's hairstyle; while I've no real intention of doing so, I feel for those who like to change styles on a regular basis. Hats are the same way for me - I rarely turned on my headgear (save for my DRK, because he had to be as edge-lordy as possible in his PVP lynxliege set), but again there are those who like their various hats. Me? I'm quite content with experimenting with different glasses and shades on my Hrothgar. So yeah, I think my final opinion is "I'm fine, but I do hope they expand options for those who want more."
As for expressiveness, I think that Hrothgar are probably the best at it by a long shot. Our emotes have so much energy to them, and they just make me smile. :3
