A successful ELO booster there are some main values that you have to dispose. The public may think that if there is a professional master tier player, that is enough for him to apply to any booster company. Well, it is enough to apply and there is a chance that he might get a trial job too. But the chance that he will become a standard booster choice at that company is very low. This is because playing well in League of Legends does not mean that you are an ELO booster who can carry games and boost an account up to a variety of tiers and divisions.
