Someone tell me how this is A+

Your farm is bad for a 40minute game Lee Sin.

What about wards? Objectives?

in the same boat....twice with lucian i went 10/0/3 with 121 CS @ 20 minutes and 9/0/4 with 169 CS @ 28 minutes. people tell me its my CS but how am i supppose to just CS when the Enemy pushes to hard and i just take the open kill and open towers? then since they fed me they wanna just teamfight right away or surrender. idk how im supposed to get an S- cause riot doesnt even tell us how we got the grade or what to even work on.....

To add to Hammerlock, the grading system is also based on relativity, including relative to everyone else in the current game. Your team has 3 over performers and the enemy team one. Could be that they're all watering you down. (To rephrase, it's exceedingly difficult to see more than 2, maybe 3 S's in a single game).

bad cs for 40 minutes game also died 5 times and probably didn't help take towers, you have to due tower damage not just come in for the last little bit

it was also a bit of a stomp; it's harder to get a higher grade when your entire team does well/the game is one-sided

Because it's very easy to get a good kda on Lee sin.

low assists jsut at a glance. I've seen bronze lee Sin's have a better record. That is what your competing against other Lee sin players not your team.

As far as I know the grading system is not just based on KD. Assits, Wards Bought (Pinks), assists or secures on various objectives (towers, dragons, barons, scuttles, buffs), wards cleared and a few other factors determine your grade. I've gotten an S on Anivia before when I went 0/2/24, but had assited on almost every single objective and had nearly 100% kill participation.

to answer the your question... when it looks like an 'A' its probably because we both received the same schooling to identify the letter 'A'

suggestion.. Die less
