Top lane relevance?
I was thinking about teleport, actually. It got nerfed because everyone started taking it. What if there was a Doran's-like item that made TP a shorter cd if.... You were 'far' from a tower. Far enough that mid laners and tower huggers don't get much benefit from it. You were 'far' from a teammate, so bot laners get less out of it.
Maybe a 2:1 ratio on a net -240 gold item? 60 health and 10 adaptive force, 2hp/5?
