Champion Rework Suggestions!

hai there, im here to know which champions need some reworks. I mean some visuals or texture updates, not the abilities.

imo, champions that need some reworks are:

Evelynn

Mundo (his w is atrocious)

Fiddlesticks (he just doesn't look very good)

Karthus (same as fid)

Malphite (Which is head? Which is nose? xD)

Poppy

Tryndamere (sultan-like animations pls, they are beautiful)

Warwick (the weird spin thing when he bites?)

Xin Zhao (he would look super badass with riot's special touchup)

Im not trying to hate, i love riot to death. Any suggestions, or disagreements? I really (not for any exact reason) want to see what the community thinks!
