A new kind of "Score"

Just a simple suggestion. But I think it would be helpful for planning, balance and performance measurements. As well as fun bragging rights. If a new kind of end game score statistic was added along with "highest crit" and "healing done" etc.

Since highest crit is aimed at ADCs, this one would be a bit more focused on mages.

Highest damage done to champions with a single ability OR highest 3 second burst dealt during the game.

What are your thoughts?
