Enemies should be able to click Thresh's lantern to travel to him as well.
Bard has this feature in his portals - he's punished if he fucks up on placing them, and he's even limited to walls with them. Granted, multiple people can traverse them, but still.
Why cant Thresh have this as well? He should have some decision making in his kit other than "I missed a hook, so lets wait for it to come up" and "I landed a hook, now press hook again and flay + ult + w the adc into range".
Not to mention it's a fucking lantern. Theres no force that prevents an enemy from touching a lantern in real life, why should it apply here?
