Here's an ult idea: an ultra-long range version of Thresh's lantern

Thresh's lamp has always been a great tool to let gankers rush into lane to surprise the enemy, but what if there was a future Support Champion with a version of said lamp that can extend, say, 4000-5000 range?

Before you say "OP!" I'd have a few major changes to the skill:

• Does not provide any shields
• Requires a channel period that can be interrupted
• Travel time for teammate would be longer than Thresh lantern, and your opponents would know someone is coming

This changes it up so it's not good for saves in conventional situations, but is meant to allow a teammate to "long range teleport" to you if given the opportunity. It works with Tahm Kench presently, though in a different operational manner.

Any thoughts?
