I noticed Sion isn't listed anywhere in the guides as an AD bruiser. With +65 AD steriods at level 9 from a maxxed enrage, I feel there are few outright bruisers who can compete with him 1v1 (especially with his ult up).
Sure, he is easily counter picked, but any time I get the chance to use him (i.e top lane is someone like Riven or Tryn or Mundo or anybody without super strong ranged harass) I completely stomp my lane. Admittedly, I'm fairly low elo (~1200) but I have completely surpirsed many players with the raw damage output he has early game.
Does him not having a single AD build indicate that at higher elo he is no longer viable at all?
