What you people need to realize
The "Damage Dealt" in the graph does NOT determine how good someone was.
You could have all of the damage in the world, but 1 damage every 10 seconds for a billion seconds means nothing compared to 1000 damage in one second.
WHEN the damage is dealt is what matters. If your damage dealt was all against minions and was over a super long period of time, while someones small damage was in bursts, that's what matters.
It needs replaced by average damage per second for the whole game.
Even then, it doesn't matter. If you are 9/7 and the entire team wastes everything to kill you in a teamfight and your team mops them up, you are clearly a huge threat and are doing your team a favor taking the hit for them.
PLEASE stop acting like "damage dealt" means something. Yes, supports can deal more damage than carries if they are split pushing taking turrets, or building gold to be a threat in a teamfight. That doesn't mean anything.
