What kind of support is Pyke?
He is an assassin first and support second. But that isn't to say this his supporting capabilities are poor. When Pyke falls behind, he relies more on his crowd control and support aspects. But if he's able to get ahead, he becomes an extra carry for the enemy team to worry about.
What position is Pyke?
Pyke is a support champion that can be used for mid lane and top lane. The mid lane Pyke builds/mechanics can be integrated for top lane as well.
