The S system is bs

Your CS also matters. Everyone seems to think only kda matters

It compares key stats to other people playing that champ in that role. Your cs was about 150 lower than it should have been.

You had 94 cs in a 28 min game as a lux I think you deserved a C consider yourself lucky.

Yep. CS, wards, and participation in objectives like drags, baron, towers etc. Also perhaps the length of the game.

I'm going to assume it was a combination of poor CS and lack of warding.

You performed good but not great

CS, kill participation and warding go into your end-game score.

I think how many objectives(turrets, inhibs etc etc) you get/help get coincides as well but I'm not sure about that.

Get Good M8.

I don't know how is it realted but here it goes. I play top and when I go ahead I'll buy a sightstone. If we win I always get an S+, always. A friend says it is bc the system starts judging me as a supp and my stats and map presence becomes extremely high compared to any other supp.

For me it seems like KDA means nothing (unless you die a lot), same with CS, what it is guaranteed that helps a lot is tower takedowns and objectives assitances.

I'm sure someone in the forums will eventually take his time to graph all these varables aginst the score obtained and find tendencies.

Terrible CS & Your average is about 9-10 wards per game.
