Sion is a pretty good tank after his rework
And that's about all he's good for. I really miss the old Sion. The Sion that you could play any way you wanted (AP or AD). I miss having tons of health late game because you farmed well. But then the rework came and you turned Sion into Malphite. I'm sure some people love this, but the people who played Sion for years do not. I'm sure certain parts of her kit were broken and had little counterplay, but when you look at some of the other sh*t you put into this game, it's the lesser of two (or more) evils.
