@riot: How to fix the dynamic queue problem
Ok.
This is so obvious I can't believe I didn't think of it before...
So the problem is that people want to play with their friends and they want it to be ranked so that there's some consistency of game play, but they can't always get 5 people together so you need solo players to make it work... But this punishes the solo players who don't want to play with random groups because of a million very very good reasons that I don't need to get into here...
So.
Are you ready for this?
...
Make a separate queue for 4v4 summoner's rift. Boosh. Problem solved.
If they want to play as 3, play twisted tree line, if they want to duo, that's fine, that was in solo queue and if they want to play as 5 they can play as 5. 4s and 5s players would gain individual mmr for the 4s and 5s queue. Teams of 4 would only match with other 4s and the same with 5s.
Health values on towers and dragons and barons could also be adjusted slightly for 4v4 and that would create an entirely different meta from 5v5.
If this option has already been considered and rejected by Riot, I would be very very interested to learn why.
