I think a texture revamp would heavily help this game a lot of the textures on the character, for example ears, feet, hands, are all very low poly same with the butt/arms SE needs to come out with a HD texture pack in order to implement such changes problem is they're still clinging onto server issues which I don't understand this excuse after 4ish years. Other things I'd like to see are:

-Dying in layers (basically what GW2 has)
-More sliders and deeper character creation
-Revamped colors in the character creation (more vibrant colors using saturation etc)
-More facial options for males/females (more facial hair for men, more makeup options for women)
-Muscle sliders for all races
-Hair styles unlocked for every race
