Why ELO/MMR ruins games and prevents people from bettering theirself as a player.

In ranked this system is totally understandble.

However, let's get to normal games (where more 65% of summoners rift games are probably played.)

1.) ELO/MMR matches you with people equal to what the player understands of the game. There is no chance of being matched with someone whom can help you significantly unless it's the obvious smurf but lets face it, who cares about anything on a smurf?

2.) Half the time, yes even ranked you get paired with people whom are playing champs for the first time, are just the below average player, or are trolls (esp in lower ELO/MMR)

3.) I'm not saying abandon the system, the system is fine. Abandon the system in normal games, not ranked q. In the end the greater result should end up in the majority of LoL community becoming better. I imagine if the tribunal was still in place that number would be better. We know what kind of people of shouldn't be on yours/our team.
