Playing against Rumble
How to counter and exploit weaknesses
When Rumble is Overheated (red bar), he's silenced and can't use abilities for 6s.
His R is devastating in tight spaces: don't fight in the jungle or chokepoints against Rumble.
Rumble is vulnerable to direct engages because he's squishy with no mobility.
MR is very effective against him: all his damage is magic.
