One surprising one I would want redone would be the ye olden elemental wing-sets because the recent spring of backwings really shows they've improved as well as finally learned the nice 3/4th view in items which basically was the reason no-one liked to wear the elemental wings because the angling of the item was HORRENDOUS.
I adore the ink wings but they really could use an update
I want another voodoo REI like Jinxi's Charm but redone with amazing wild hair, cool tribal tattoos (Like Jinxi, but maybe in better colors and with more intricate, ornate voodoo designs). Maybe some interesting backgrounds...There was so much potential in Jinxi (And don't get me wrong, I still like it) but a lot of it was spent on headdresses.
It's kinda weird but I'd like to see Staff of Angels to be a bit softer. And have pose for only it glowing in addition to its non-glowing state. And then the Elemental Wigs could do a good remade pixel too. I would love to see the water and wind/breeze hairs more flowy.
