Please, someone, explain wtf is this?
I don't understand how these ranking and rewards work.
based more on just kills, deaths, and assists. it's based on CS, champion. lane. etc
KDA is a red-herring. I don't know how ranking works on dominion, but it probably looks at things like damage dealt and damage taken along with several other factors, so don't fall into the pitfall of thinking better KDA = better grade, because as you've seen it's definitely not the case.
Hextech keys are granted solely on wins and are not affected by any other factor. Drop rate on them is non-linear and resets roughly every 30 days, so you'll get a lot after they reset and as you obtain more the drop rate will dramatically decrease.
As for how you get your grade, they use more than just your KDA. Things like warding, cs, objectives, damage/healing etc. Nobody knows what exactly is needed but they say you wouldn't be surprised by what is used. You are graded by being compared to all other players on the same champ in the same role. If you don't get a high grade, that means at least one of your scores was too low and dragged it down.
Time is a factor as well (otherwise the shorter the match the lower grade you'd always get no matter how well you did). In other words 200 CS in 20 minutes is much better than 200 CS in 45 minutes.
You are graded against other players playing that same champions, if you don't get S, that just means other players are playing that champion better than you.
