Cloud soul is underrated. People don't understand how valuable movement speed is... Riot nerfed Karthus by lowering his movespeed and now people are already not playing him. His winrate went down 3% from 5 movespeed.
You're the first I've seen even note that cloud soul has movement speed. The damage reduction on a skillshot you dodge (or enemy team collapse you escape) is 100%.
