Match-up with Sion
I have been struggling whenever I faced Sion on top lane. He never seems to care about fighting and would start doing proxy and roaming around. If my jungle/mid doesn't gank Sion will always outgold me and the gap gradually becomes bigger over time. And when it comes to team combat he's just more mobile than me so I can't take advantage of that.
I tried building more damage items so I can clear minions faster and roam around to control the map but it just doesn't have the impact I need. So most of the time I have to wait for my teammates to make a difference and play well in team fights to win. I myself never seem to be able to outplay him in laning phase.
What would you guys do to counter Sion?
