Is this the worst performance on a single map we have seen in a while?
Just for reference, assists (including utility assists) are much more impactful in the rating than in ACS. Analysts have done some number crunching with ACS and it pretty much exclusively favors yoloing at the enemy with pretty much every supportive/utility/teamplay/clutch element of the game having little to no impact.
Btw, the rating has a built in function to asymptote at zero (if you were around during the first week or so of the rating being out you might have seen some negatives). Numbers less than 0.05 are slightly higher than if the rating was allowed to be negative. It wouldn't change much anyways since only the very worst games ever went slightly below 0.05.
