I've been wanting Riot to do something like this for the longest time. A friend and I discussed this idea awhile back and both thought it would be a great idea. If you can get Riot to do something with this concept I'd love you forever. <3

The system is fine. The players are the issue. You can't just build your system in a way that removes choice and creativity just because every player thinks they 'need to carry with mid'.

Debating an idea is the best way to perfect good ideas and filter out bad ideas

I feel like this enables you to play what you desire, I think that's the main point of this. And of course, you have to think of que times, arguably the most popular roles are top and adc. So if you choose top or adc, you will have a longer que, than someone who wants to support, or maybe choose all roles to play. You wouldn't have to be limited to all roles, you can choose however many you want and which ones you want.

I think that people being able to choose what they want to play would further creativity and literally expand choice.

Yeah but you can have a good, friendly debate, and an argument lol.

Because it doesn't allow for the intricate selections that can be made, I don't play top, but if I notice an opportunity to counter pick someone hard with one champion I am good with. I can do that, but I don't want to select top as one of my viable options.

The fact that there isn't an actual "team setup" that is required to win also is important, in WoW you aren't clearing dungeons with 5 rogues, but 4-5 AP can certainly win games in league(which ive done, even at 1800)

The idea of "voting on the meta" is a great way to illustrate that you don't really know what the meta is and how its developed.

Solo queue is your individual skill rating across all roles(weighted by frequency of playing them), if there were ladders for different roles it would be one thing(of course that wouldn't work because roles are dynamic even during the game)

There's 2 things here.

First you haven't actually showed that the elo system doesn't properly place players, sure there are times when you are a little lower(or higher) than where you should be, but you, or anyone for that matter, have never really made a good case that the elo system is placing players where they don't belong.

Second, you haven't actually thought through the idea of awarding bonus elo for assists have you? Many players would do actions to abuse their stats to gain elo. Think about that for a minute and then come back with a good explanation of why we should have bonus elo for assists

Well, for the intricate selections being made, I don't think that your example will be impossible to happen again. If someone has trouble with the champion they'll be up against, they can see if mid will be a better top or if anyone can? It's just a surefire way to eliminate the games where people instalock 2 adcs and everyone just has a bad time. And the meta is what the norm is. Professionals agree upon the meta, and everyone likes to follow what professionals do. Whether we vote on it, or pro's tell us what it will be, it's just going to be the same.
