to me, hulkbuster does not make much sense in the comics. why would tony try and go toe to toe with the hulk when his regular armor has the advantage of being way more nimble?

he could fly around hulk, blasting him from a safe distance, or hit him with a knock out gas or something.

thinking that the way to stop him is to try and match his unmatchable strength is pretty dumb if you ask me.
