I have no idea what more I could have done that match to get a better grade. I know that the grade you get at the end doesn't really mean much... but when I play the best match I have played in a long time and get an S- it is just a little disheartening.
Objectives objectives objectives and high gold income
I don't know how to say this without sounding whiney, but 12 kills on Kha isn't that high. In a lot of games I see him 2-shotting people.
Reminder that ranking is based on a comparison between you and other players who played that champion in that role. There is no one thing fixes all as far as rankings go. You just perform better.
Okay so, S+ and S rank in general is not predicated so much on your kills, but rather your deaths, your CS, objectives taken down. Don't feel bad, the ruleset S Rank enforces doesn't empirically mean you're bad or good, but rather whether or not you fulfilled it's arbitrary requirements.
be greedy try to get every kill tax lanes steal last hits on wards from your team generally anything you can to make sure you get the S+ (and nobody on your team does)
do the rest of the stuff you usually do to get an A - S rating sure it is unsportsmanlike, but that is what riot promotes with individual rather than teamperformance ratings [sg-ahri-2]
