An Idea for Teleport

Kind of like toward the end of Season 5, is being used by practically every mid/top laner for the safety/play-making potential it brings.

What if you raised the cooldown to 400 seconds but added this: "If you get a kill/assist within 10 seconds of casting, cooldown is reduced to 200 seconds." The CD reduction to 200 for cancelling would still be there.

That way it'd discourage using just to get back to lane and make laning counters more meaningful, while still rewarding using it to help your team.
