I really do not understand how i did not get an S this game i have had some questionable S's also. I mean i dont entirely care but that was the game to get my last S for akali and get her lvl 7 :( Stats: http://imgur.com/a/qVSRF
I don't really believe they should put so much value into it, but I'll say it before someone else does. It is probably because your CS is low. I wish this wasn't the case because farming jungle or your lane when you are way ahead doesn't make any sense. It is a lot more useful to roam and help your other lanes when you are ahead rather than farm in most cases.
You're not showing all the stats, but I do see that your CS was terrible.
I notice that you fail to show the bottom half of the stats. You probably didnt ward much and didnt buy pink wards (how I miss thee)
Let's put it this way; EVERYTHING you can do in League, whether it be placing wards or taking damage, goes towards your grade. However, depending on your champions main role/where you play them also goes towards your grade. For example, going full ap Sona "support", with no support items, could get you a better score than actually going support Sona, however taking her mid would get you a better grade as full ap Sona as then you can actually cs without the adc getting mad or falling behind.
