Rumble is honestly a garbage champ
We have a magic dealing champ that basically needs to be in melee range to do any sort of meaningful damage. And when he finally gets in melee range (IF he manages to get in range without getting blown up) he has almost no burst, so he usually just dies. He has almost no mobility in hit, and the range on his abilities is terrible. I'm not gonna sugar coat this. Rumble is a garbage champ. Don't pick him ever please.
But if Riot was to buff him, make his ms boost better, make the shield better, reduce his cooldowns, or increase the range on his harpoons and ult. If Nidalee can throw a javelin halfway across the map Rumble should be able to shoot his harpoons a little bit further.
