Themeatically, Thresh's "Dark Passage" makes zero sense.
A warden from the shadow isles who entraps souls, drags people to their doom and flays them alive while giving them no escape.
"Oh shit my ADC is in trouble, quick click this!"
Why does a support with some of the strongest initiation tools on top of some counter initiation and decent scaling -also- get a "Get out of gank" free card unless you wrap your fatass hitbox around the lantern and sensually grind on it until thresh walks away in disgust so the adc can't escape?
Can we at least give this tool to another support and replace it with something that makes sense more thematically? Because Thresh is the last person I'd expect to save you in a scrape.
