Fun discussion i had with a friend, is any hero viable mid? I said yes, he said no, for example omni wouldnt be good mid. What do you guys think? Imo any hero is pretty much viable mid, as omni that early level 4 heal nuke is incredibly strong, not only for damage but sustain in lane aswell. Also repel just stops all ganks, and against most magic based ranged heroes that just stops them from killing you completely.
One could say Chen would be bad, but get a harpy or wildkin from jungle and enjoy harassing the other mid, with max pure damage nuke aswell. Harpy itself would kill any opposition.
Wisp is pretty good mid, early relocate is really strong and before that the spirits actually deal a good amount of damage.
