What's the point though ffs. These trash low-tier Master peak players drop 200-400 LP and the matchmaking is so dogshit it still pulls them into games under 800 LP. If you're gonna do this, fix the matchmaking system too. I don't give a fuck if it takes 10 or 20 minutes, just match people with the same LP ffs.
Or just do a hard reset and make everyone start from Emerald 2. If you drop those first-time Master peak shitters to Emerald, they'll never climb back out, but the actual Master players will have no problem getting back up.
They say they can't climb because they're mixed in with those guys? That's because those fuckers weren't even Master level to begin with when they climbed, they just didn't realize it.
