Suggestions - Changes to matchmaking (Requesting constructive discussion)

1. Change match making so that people have the option to wait a little bit longer for fairer match making. From my understanding on how matchmaking works by reading it on the league wiki, if you are in queue for a longer amount of time, it will broaden the skill range of people allowed in that game to find a game quicker. This can be useful for master/challenger players because it takes them a long time to find a game anyways, but for lower ELOs it really isn't necessary. If possible, it would be nice to have matchmaking options to avoid more unfair games. The 50 minute close games are much more fun than the 20-0 at 10 minute, completely one-sided games. I believe adding this option will help people feel more satisfied with their games, even if it's a loss.
2. Allow people to be able to only choose one role, instead of forcing them to choose a secondary. I realize that this feature this season is already really nice, and I'm grateful for it, but it could be improved. What if I want to choose all roles except for one? There currently isn't an option for that. I feel like making the role choosing part a "check box" of sorts, where you can check a box next to each role/fill, would be much more efficient. And to conclude, I believe the root of these two issues is because the game prioritizes finding a game quickly over it being fairly matched. Personally, I wouldn't mind waiting an extra few minutes if the next 20-50 minutes will be a game worthwhile. Thoughts?

P.S. Please let me know if and why any of this wouldn't work. I would appreciate it if I could receive an explanation instead of just a downvote and an ignore. [slayer-pantheon-thumbs]
