I'm an Elo booster and regularly boost accounts from as low as what is now "Bronze V" up to anything around 1700.
My winrate below 1500 is ridiculously good and I carry disgustingly every single game without fail. --- "I've already told you: the only way to a woman's heart is along the path of torment. I know none other as sure."
Kind of not important but bullistic was reep's original get out of elo hell on which he built carrystar and Aruarian Dance was tinker's. They DUO every game. In most of their games if they were to play solo they would not be able to carry (just watch them and they 2 man the other team while their team feeds and throws, but they feed each other and without someone to work with I don't think they could win some of these games)
ya these streamers who play in the low elos purposely I see them have a duo dont know of one who goes completely solo in their climb. (mostly cause i watch very streams i guess)
