Challenger in season 3 is not an actual tier explained.
Challenger in season 3 is 15 of the best players/teams + 35 of the players/teams who spammed games last 3-4 days. My team was ranked 23rd in NA challenger and we have been there for around a month now. We have higher mmr than almost every team except 10-15 teams ( we are always purple side with the disadvantage, we only had blue side vs team wazabi.) We beat the top 20 teams 2-1 usually.
Our mid laner has been busy for the past 3 days and can't play. We were 144 pts and we just lost our spot because someone managed to get in promo series in d1 by having higher mmr than the LOWEST team in challenger. We have guaranteed higher mmr/elo than half the teams in challenger, but it doesn't matter. We were kicked out 5 hours before the ladder ended, 12 hours ago, there was 7 teams under us, thats why we didn't want to mess with our midlaner's schedule. We had almost no time to find a sub, but we did, and we got back in promo to end up 2-2, unable to even finish the last game to decide if we win or not because we got outplayed by Riot's LP system.
43 new teams were recruits in 3s. And over 30 soloq/5s teams are recruits. This shouldn't happen.
