Letter Grade for Jg is absurd.
A game where I virtually punish the garbage 4 man I got put with who didn't help me at all on an early start 3 man invade on my blue while they chilled by their turret. Got called boomer by the Akali and chimp by the Draven who got fed.
I went full AFK farm mode, didn't help dragons, didn't help baron. Just pure AFK farm and sidelane soak to spite them and make the point that if I don't get help they weren't getting help.
They were on the verge of losing since as fed as the draven was they could not win a 4v5 late game with a Leblanc Akali fed and a Kennen ult combo with Kayn.
So I got bored of the game and started landing snowballs on leblanc and helping them take 2 infernal drakes and elder dragon whenever they weren't busy trying to brute force the game while calling me useless for returning them the favor of not wanting to help for selfish reasons.
We won the game when I actually showed up by the skin of our teeth since by then they had fed the Varus and Kennen enough kills to pose a threat.
And for a game I intentionally made hard since that 4 man said I was a chimp and didn't need me only to later rage at me for being "useless" while I farmed?
I got an S for barely getting involved in objectives and skirmishes/teamfights for literally 90% of the game. Pretty much close to 40 minutes of farming got me an S, as compared to other games' B- where I actually strive to have early impact on a map.
And come to think of it, playing this selfishly is the only way I've managed to stay on the same level as my laners and get items just as fast if not faster than them. By just AFK farming, not doing objectives, and zero interactions with my allies or the enemy. It makes no sense whatsoever that this kind of playstyle is rewarded.
