How does Rumble's Heat mechanic work?
I know that when your heat bar is yellow you get bonus stats to your basic abilities, but what I don't know is when those stats kick in.
For example, if I do QEW right off the bat, the bar goes yellow. Do I get the extra move speed because W pushed the bar into the yellow? Or does the bar need to be yellow when I cast the ability to get the bonus? What about if the bar turns yellow while an ability is going, like Q or in between E's?
