Cho'Gath Mid actually used to be his main role in Seasons 1 and 2. The problem with him in lane, though, is that all of his attacks are AoE and so push the lane a lot, which makes him vulnerable to ganks. The meta also shifted towards more mobile and aggressive mid laners, which are the champions Cho is weakest against.
