[GAMEPLAY] Control Wards may not be taken into consideration for mastery grades

Not sure if this is a bug or simply something overlooked, but I feel like the new Control Wards (purchasing/using them) aren't being taken into account for determining the grade you earn each game.

My reasoning for this is:

(1) When viewing detailed information of my matches online, under the Wards section of the Statistics tab, there is no row for Control Wards. The rows for "Stealth Wards Purchased" and "Vision Wards Purchased" are still present (likely so players can still view that information for games prior to this preseason), but there's no way of knowing how many Control Wards I purchased. This missing piece of information is the main reason why I'm afraid that Control Wards aren't being used when calculating your grade.

(2) Before the preseason changes, I had no trouble earning A+/S- grades when playing as support, a role where I frequently bought Vision Wards. But after playing several support games since the preseason began and Control Wards were introduced, the highest grade I've been able to attain is an A+, even though I am now buying as many Control Wards as I used to buy Vision Wards. I'm still performing as well as I used to as a support, I feel. It's just rather frustrating to have not seen so much as an S-.

I don't mean to sound like I'm complaining about not being able to earn S ranks as support since preseason began. I just want to make sure that Control Wards aren't accidentally being overlooked for grade calculation.
