Hello! 
Welcome to the Forums! 
First off, it’s a dupe. Link here
If what you mean is “put people of the same skill in lobbies with others of the same skill”, this wouldn’t be that good of an idea, since there arent too many prestige 5s playing at once. If you mean “put people in queues of people using the same platform” it’s a better idea, but this would mean that you can’t play with your PC player friend if you’re not on PC, which would be really annoying.
Overall, not a good idea. I will not be voting. Tip: you can vote on your own topics.
Have a great day!
