Stop putting new accs in low gold mmr.
Gold 3-4 has felt like a coin flip for the most part. For many of the games it seems it's whoever gets the unranked player on their team doesn't win.
In addition to that, I recently had a game with a 40% win-rate silver 2 adc was matched with a gold 3 adc main, and the silver wasn't dued with anyone. Why cant they put people where they belong.
