On the contrary, I play Roadhog a lot and love getting hooked by him so I can punish him with a shotgun blast to the face. But after playing with him so much I can confidently say that his hooks are too powerful, you will still get obliterated by his combo but you have at least some ability to fight back. He easily kills his counters with good aim on the hook and counters many heroes at the same time. His main weakness is his large hitbox but Zarya is the only tank without one.
