Riot your Normal game system needs to be refined

Right now normals work on MMR just like ranked, but it also seems it employs a weighted win/loss system if you are losing/winning too often ( not going to talk about this so chill skeptics )

How many times have you tried a new champ in normals just to get completely shut down by a mastery 7 spamming enemy? How many times have you played a new champion for someone on your team to just completely destroy everything barely even letting you play? Both learning nothing about said champion? Most normals I experience are over in the first 5 mins, you will see a lane get completely trashed and it just snowballs to other lanes and it's over before you know it, but you can't really blame some people, they just want to try unfamiliar things and get reemed for it.

Teambuilder was the right direction for this because you locked in your champ before the matchmaker even started , now we have a champion mastery system, couldn't both of these aspects be joined to make for a much smoother system designed to improve For example, you lock in a champion you have never played and the system sees this, it will match you with another player who is around mastery 0/1 for you to play against, same if you locked in a M7 champion.

It may take a little longer to make games, but I would be willing to wait a bit longer to not waste countless matches to truely experience a champion I have never played before.
