Something I would like to see is high level, untradeable crafted gear. While high level sets like Vanya and Darksteel are appreciated, they are necessarily crippled from being the best items due to being buyable (Hence why the highest sets are 70, not 90). SE doesn't want someone to just wrangle up a bunch of gil and buy the best weapons and armor in the game. I've made such an argument in the past, and usually get the response of "If I can't sell it to make money, what's the point?" and "Why should I need to level a crafting job to get the best gear?" Well, the point would be having great gear, and if you don't like to craft there's plenty of other high level gear you can obtain.
