Something to consider about outplay potential
When burst is given too much outplay potential (spread out, made too conditional) then the classes burst is meant to keep in check (squishy DPS) are going to rise in relative power. More often than not, the champions best equipped to deal with abilities that can be outplayed, since Riot's favored form of outplay potential is 'dodge the thing', are the ones more mobile than average.
Now, remind me, which champion has single-highhandedly been stomping Worlds into a rocket-jumped crater?
