Can I get an S rank now...

I remember a game where I received no deaths and had a good portion of kills and assists, but still only received a A+ rank.

Just hop into an LFG chat channel and grab 4 people from there. If you play a 5 man premade someone is bound to get an S within like 3 games.

Your farm was low so you didn't get S. Pretty sure you need like 8/min for S and you were about 100 off of that (didn't actually so the math, just a guess)

That Garen makes me so sad... If you know him please ask him why he has a Nashor's Tooth for me, I really want to know.

You had less than 30% kill participation and this shows nothing about warding, turret kills, inhib kills, dragons, barons.
