To be frank, I'm tired of how everyone looks like a cookie cutter of their chosen race with different decorations. I'm not implying that proportions should be changed or that there should be limb sliders (I've played enough Aion and Blade & Soul to make me actively NOT want that), but I like the "athleticism" slider Okamimaru suggested.

I want to see chubby characters, or just some sort of body alterations beyond height and breast size. Everyone looking like a barbie doll is boring.
