When your retarded teammates listen to retarded shotcaller

Just finished a game of doom bots, it's easy with a cooperative team. The game i played before this one was very frustrating however. I pinged teemo and cait to help me get blue as lux to help with the early levels, for some reason the retard xayah told them to not come help, calling me an idiot since the buffs came to lane anyway. They left me and i couldnt get it level 1. The xayah then proceeds to call me a bad teammate for leaving teemo alone for 5 seconds, after the retard died jumps in head first into veigar and malz bot. I tried to ignore her blames and carry as much as i can, went something like 16/4, but we ended up losing anyway with the retard xayah going 8/16, the worst score out of all of us.

This was just doom bots, i can only imagine a ranked game with people like these. I still don't get it, would me taking blue hinder her performance bot lane or something? Why do people only listen to retards? Sometimes i feel like league is a game of chance, only if you're lucky to get teammates with a brain you can win
