We need... a hair update.
With Pantheon's rework planned to be the last big VGU, even despite the fact we still have utter atrocities of design like Mundo walking around, it came to my attention that a lot of the older human designs have one problem in common.
#The hair.
A lot of it is poorly modeled and poorly textured. Olaf being the most horrendous example, seeing as the problem is shown not only by his hair but his beard and all the fur on his armor as well. Worst of all, he's supposed to have his beard tied and it's actually just one solid triangle shape with a poorly-drawn hair tie in the middle. It's completely ridiculous to leave his default and three of his skins with such terrible models when every new skin has them fixed. (as you can see from the pic below)
That said, I reeeeally hope they don't just call it good with all the terrible models left in the game. Hell, back to Olaf, he doesn't even actually have fingers. His hands are solid mitten shapes with finger lines textured in.
To add insult to injury, his newer skins actually do have fingers, and Brolaf's right-hand bracer, as you can see, is actually just a tuned-up version of the default's incredibly crappy one.
