Buff Rumble?
I used to main Rumble back in season 6, but due to changes in the mastery trees and heat management. Rumble deserves a little love too. His early game has become too weak against the bruisers that rule the top lane and tanks like ornn or maokai don't have a problem against a champion that does damage over time. Additionally, as one of the best top laners seen in Worlds and in any professional league, he is now sitting at a 48% win rate. Personally, I think a change such as adding a slow to Rumble's Flamespitter or lower the CD of the equalizer will put him back in the meta. Increasing his utility would shift him to be sort of a control mage in teamfights. don't think there are any changes that can be done unless the meta is shifted. Let me know what you guys think!
. I think one of the biggest problems Rumble faces right now is not being able to stay in a fight long enough to do his damage without getting one shot. That's why I tried this out and haven't gone back since.
