Players should be able to queue up for as many roles as they want.
I have been thinking about this for a while and i think it would be beneficial for everyone.
Right now you HAVE to queue up for 2 different roles or choose Fill. So either 2 or 5 roles basically. This makes 0 sense.
The playerbase is split up in 2 different groups. One-tricks and people who are willing to play many roles. And One-tricking is only becoming more popular since many players have found what lane they like and what champion(s) work best for them. But the matchmaking system is not optimized for this.
Lets say that I'm an Evelynn main. Evelynn is an example of a champion who generally only works in one specific role (jungle in this case). So if i only want to play Evelynn i have to queue up for jungle and 1 extra role that Evelynn will not work in. What this leads to is a lot of dodging in champion select. And i really hate dodging since it wastes the time of 10 people who now has to wait for a match again.
And then there is the other group of the playerbase who often has a preferred role that the want to play, but they are willing to play other roles if their preferred one is occupied. And most player also have a role they they prefer to not to play, ADC is a role that i am very bad at and really don't like so i try to stay away from playing it as much as i can. I would for example like to queue up for Jungle/Top/Support but right now that is impossible for me to do. So right now there are no options for people who wants to play 1, 3 or 4 different roles.
This change would be beneficial for both these groups, it would lower the total queuetime for the majority of the players and it would lower the amount of dodging that happens right now in champions select.
