props on the sion rework
he's actually extremely fun to play(i had my doubts after watching him). he's a tad on the really strong side, as stacking hp is all you have to do to become a monster that no one can kill. his passive i found to be meh though, as everyone just runs away the second you die and kite you. his e is very nice and rewarding skillshot mechanic(like syndra's w) and his q is fantastic for buying time in a fight until your team shows up.
w, e, q, w, r seems to be the most effective skill combo.
