Can we talk about Thresh?

There are certain things in his kit that have no counterplay, and it's frustrating to play against. I'm not asking for straight up nerfs, I'm asking for reasonable counterplay. If you can justify why certain things are as they are, I'm all ears. Don't give me explanations like #LC$BIGPLAYS.

Lantern - Once you see him throw the lantern, you know that you kill is going to get away. There is no way to deny the lantern other than to kill the enemy in time, disposition them away from it, or CC them until it goes away (Lantern lasts SIX SECONDS). There is no counterplay. It's frustrating to play against this. Maybe we can deny lantern by having one or two people stand on it. I don't know.

Death Leap (Q reactivate)- Sure, I can prevent this by dodging his hook. I just want to know why I can't knock Thresh out of death leap. You can knock Lee Sin, Leona, Akali, Jax out of their dashes, but not Thresh. Why is he an exception?

Could anyone offer me an in depth explanation as to why these designs are in place?
