Rumbles flamespitter needs to feel smoother

I been playing rumble since season 3 and it bothers me how his flamespitter does chunks of damage instead of draining the health of minions and champions. It needs to do damage every 100 millisecond.

For example, if your flamespitter damage says 500 over 3 seconds. Instead of 150 every second or 75 every half a second, it should to be 15 per 100 millisecond or .10 second.
