This is pretty much it. I carried myself out of Bronze V to Bronze 2 with Akali single-handed. I got shitty ass teams but the other teams were shitty as well.
Also, there IS an ELO hell in just about each ELO. It's pretty much different for Each... section? (ie. bronze, silver, gold, plat, etc) Bronze has the people that jump straight in at level 30 with no runes, no ideas of how to use masteries, or just the unlucky people that keep getting matched with those people but are unable to carry themselves out. ELO hell exists nonetheless. ELO hell is where your teamates are just... absolute shit with just bad people and leavers
rs. In ELO hell, I recognized, "THERE IS NO WAY IN HELL THESE PEOPLE WILL EVER GET OUT." The teamates I experienced were all hard-headed, rage quitting, idiots. They couldn't take simple commands, couldn't ward, didn't know about positioning, thought CS was just stupid shit, and just... absolute terror.... lol So idk how lucky you got or how good you might be (I am a platinum player :P been playing since near open beta of LoL) there IS infact an ELO hell. Also, ELO hell in like Gold would be... boosted people or just idiots lol
