Rumble is very weak early levels. Aggressive champs like Riven can go in 1-4 ish and clearly be ahead. Rumble also tends to push the lane with Q more than he wants, and you can exploit that by having the jungler come or threatened to come. His damage comes from Q not only being overheated, but hitting for as long as possible. If he misses a few ticks and you have the right champion, you hug HARD to his nutsack and make him pay for it.Does Rumble even have a bad match up in top lane? Like, from what Ive seen, his hardest match up is Diana and that match up still feels even.
He's still got strong laning obviously, but he's doable for some characters and for some that the MU isn't "great", you can abuse the likely fact that Rumble will push the lane.
