High Plat / Low Diamond such heaven for boosters.
I feel like Solo/Duo Ranked should just purely be Solo to create a more balanced environment for the players. There have been so many games that I've been in seeing so many accounts that have 0 records of last season and suddenly are in plat with an 80% win rate. Those duos could be masters/challengers playing and poor plat "trash/toxic" people who don't know how to play the game just keep getting rekt and goes afk, feeding etc. whatever you call it. It's frustrating at times cause you feel the game is just not fair.
Overall, boosting gets people upset and promote toxicity and I don't think it should continue to be what it is right now.
