What is Sion? Is he a tank? Or is he a bruiser?
I've been playing a lot of Sion lately ever since his rework and I find him one of the best, and safest top laners to date along side with Gnar. He essentially has no weakness, and here's why.
His E deals a lot of magic damage to champions that are behind minions. 70 magic damage at level 1 that can deal 105 magic damage if unit is strucked by an E'd minion. All for a low cost of 35 mana while having insane Nidalee like range and slowing them
His W shielding him for around 10% of his max health and dealing 10% of their max health as magic damage.
His Q, which is really one of his only faults, has a good AD scaling while bringing knock up and a stun if channeled for long enough.
His R that can also equate to a "get out of jail free" card. Being completely immune to CC which equates to him having one of the best escapes for split pushing.
He also has one of the highest Health regen in the game (10hp per 5 seconds).
He is able to build pure tank while dealing moderate to decent amounts of damage. With his W passive, he is able to build pure armor or magic resist items without sacrificing the added HP the other items would give. Allowing him to increase his effective health exponentially. Especially with his W being able to shield him for 10% of his max.
So what was Riot's intention when building him? He is an extremely effective tank while being an effective bruiser. He is able to fit both roles perfectly without suffering from anything. If I were to wanting to choose a tank, why would I choose Mundo or Shen over Sion? If I were wanting to choose a bruiser, why would I pick Darius or Wukong over Sion? What exactly are Sion's weakness? Because I cant really find any.
