Every single game has 1-4 fresh accounts with giga inflated mmr. Win 3 games in a row and you play with plat + emerald on a lv 30 account.
There is no good outcome when you have these guys on your team. They are either a player that is “smurfing” in the exact same elo as their main account but act toxic as fuck becuase they think they are this rank because of bad mmr or some bullshit. They can flame/int/troll how much they want and you can’t talk back because they don’t care if their 5€ account gets banned. The account costs less than 1 skin.
Or they are just complete shit silver players who got lucky first few games on the account and riot now gives them giga mmr for no reason and they get complete gapped and ruin the game.
Or you get the rare actual smurf diamond+ player who probably makes the game a one sided stomp but they will also troll instantly if their team is letting them down.
Smurfing is cringe either way but holy shit i can’t stand these guys just hopping from account to account trying to luck into the rank they want flaming/inting/trolling anytime they are not given a free win by their team.
If you bot a account to 30 riot has no idea what skill level you are / the buyer are. Because they don’t want high level players to ruin 100s of games which is what happened if they started in iron with regular mmr, the first games on your account have massive impact on what mmr games riot will give you. Just get lucky and go 5/5 in your promo games and you will have extremely good mmr just by being lucky.
