Attack speed or ability damage mastery on Top Sion?
So I have problems with last hitting on Sion. I usually play him jungle, so I don't lose CS unless someone steals it. But in lane I have a tough time grabbing my CS. I think it's because of his slower attack speed.
Would it be fruitful to use the tier 1 attack speed mastery on Sion over the ability damage one? Or should I just practice CS in customs (which usually lack someone poking me).
