Thresh's Lantern is better than Kayle's Intervention by far
Thresh's lantern is probably the most broken ability in the game in terms of how well it saves allies. Recent poll that was conducted http://i.imgur.com/UMeoou3.jpg
Thresh's lantern is so strong as a basic ability that people would rather have a thresh lantern over Kayle's ultimate to save themselves. That's how strong it is, a get out of jail free card that forgives incredibly poor positioning and has little to no counter play nor any risk associated with using it.
The lantern is in a league of it's own with regards to how well it saves allies, not Janna, not Soraka, not Morgana, not Kayle can compete with it using all of their abilities.
The lantern needs to be nerfed in some way as it's horribly broken in it's current state.
