is very good in teamfighting as well as in lane, his overwhelming AoE damage allows him to easily win trades, and turn ganks around for an easy double kill. His ultimate "Equalizer" is, in my opinion, one of the best teamfighting utlimates in the game. If you hit a good Equalizer you can single handedly win a fight for your team, even 4v5!!!

Rumble is relatively weak against champion with gap closers and good brawling abilities, such as Darius or Rengar. His early lvls are ok but not amazing. If you are not careful, u can give up an early death. Lvls 1-5 are weak.
