Went 17/3/11 and got an A+ because I didn't CS for a couple of minutes
Because I was spending time securing objectives like inhibitors and Dragons and Barons instead of mindlessly CS'ing the entire game. The difference between my CS and the highest was about 20-30 CS (190ish vs. 220ish), even though the Gold per Minute was about the same as the people who got S grades because of Draven passive.
Riot please fix this. I contributed as much as the players who got S grades, even more because I solo'd the enemy inhibitors and somehow that doesn't count as much as 20 minion kills? Come on now. How do you expect people to earn Mastery tokens if the mastery system is so unforgiving in every aspect even if it doesn't make sense?
Edit; LOL just took a look and my GPM was MUCH higher than anyone else's... What is this grading system?
