Low Elo/ Elo Hell: What I personally think should be changed.

The number one major complaint the majority of LoL players have are "teams feeding" or "afks" in ranked. This is pretty much in lower elos and gradually gets worse as u go from plat to bronze. Im a Silver player who started B5 this season after going 5/5 in my promos. Im going to start by saying I do believe most people who complain about elo hell are not good at the game, however i do believe some arn't.

Here are some of my opinions on what riot could do at address the "elo hell" problem:

1. ranked should be a privilege- even bronze players should have to earn bronze. I think having to win a certain amount of games in your provisionals is a good way to separate awful players from not SO bad players. saying a player has to win at least 5 matches out of their 10 would get rid of the people who cant even do that from bronze.
2. In specifically bronze/silver just to separate people more, make a lower/void lp loss if you have, lets say a kda of over 4.0 but still lose the game. I say this only because these are the people who are good mechanically at the game, but dont know how to carry a game. if you split them from people who are bad mechanically they will be against people who have the same problem and i feel it would be much less frustrating.
3. LOSS PREVENTED FOR AFKS. Seriously i dont know why this hasnt been implemented in all elos, but it confuses me. sure u could just tell the feeder to afk so your team gets loss prevented, but riot could easily make it so if the person afked, lets say 15 min before the game ended, its loss prevented for the team who lost.

Im not just some guy whos complaining about elo hell (although i am a support main ) i just want to put some ideas out there so the community can be better. I know this problem will never go away entirely, because bronze will always think they are better than everyone and nobody can learn from mistakes. Tell your opinions and or thoughts below.
