Help a support out.

Okay, I am writing today because I think that there is an imbalance in the post game grade, which is used to reflect on that players game. For example, I can go 0/0/12 as support and only get a B+. The problem with this is that there are many people trying to get mastery levels 6 and 7 and it seems it's impossible to get "S's" when the objective of the support is not to get kills but to assist in the killing. I feel that if assists played impacted the grades more that supports wouldn't have to worry about taking kills to get their S, and when people see a support with 5 or so kills they get agitated and begin being get toxic towards the support who is only trying to get their S so they can get mastery 6+, also the support would have kills that could go to someone who can change the tide of the game when it really matters. In conclusion, If Riot made it so assists impacted the grade enough so that it's more possible to get an S when someone is playing support it would reduce the struggle supports have in getting mastery 6+.
