Creep Score Should Be Removed From the Grading System in ARAM

I'm not sure why creep score is even in the grading system for ARAM after the latest updates to the gamemode. Now that we get ambient gold from minions just dying near us without getting the killing blow, it makes CS irrelevant on most champions. Case and point, if I get a champion like or chances are I'm getting nearly no cs. Yet, I'm still graded on it and it makes the difference between an A+ or S-. What do you think? Maybe I'm just salty about all the A+'s I've gotten recently, who knows.
