What about giving Thresh's Lantern health and defenses based on a fraction of his own?

Saw a few threads popped up recently trying to add weakness to Thresh's Lantern (they're not bad but still kinda meh), and I was curious as to why no one suggested just giving it health and defenses?

This way Thresh players would have to be a bit more careful with using the lantern during fights, and enemies have a chance at stopping escapes and stuff if they can kill the lantern fast enough.

Plus it'd encourage Thresh to build more defense/health since his lantern's health/defense would be based on his own.
