Assassins mid lane are ungankable
You should display a hint to junglers to avoid mid when the enemy mid laner is something like Leblanc or Akali because unless that player is 1-2 leagues below the rest of the players, it's IMPOSSIBLE to gank them. The only time you can kill them is when they blow everything to kill your mid laner, and at that point its 1 for 1.
I don't see how that's fair or fun. Mages were supposedly nerfed because push and roam playstyle was too safe - yet some of these assassins are literally immune to ganks unless they're diving you.
