I mean.. I'm not saying I'm pro or anywhere near it. I've had my bad days and I get all that.
But every time I play with this certain group of people, we just lose terribly. I'll carry them most of the game, I'll go maybe 15/4/5 or something, but they've just fed so hard that there's no way to even stop the enemy team. They have absolutely no map awareness, and blow all their ults just to secure one kill on a person who got caught, so when their team catches up, they're caught with all their abilities on cooldown.
I mean they're funny and cool and all.. But every time I play with them I just cringe at their poor choices, like taking Riven bot as a support, or rushing Homeguard on their Berserker's Greaves for jungle Nautilus.
