We all love this game, and we all want it to grow and become something that is widely adopted by gamers everywhere, so the community is healthy and there's always loads of people to play against... therefore I'm throwing out this suggestion to see what the other redditors (and hopefully someone at Valve) think of it. I think this may also lead to part of a solution for casual players who don't have loads of gamer friends to queue with (or give them another way to meet some).
What about a REAL solo queue mode? This has been used in other games for years. Essentially you can queue in this mode, but not with a group, so you know your team is going to be 4 solos and you know you're going to run into 5 solos, and the hope would be that valve's matchmaking should even it out pretty well from there.
This would eliminate group pubstomping, or group smurf pubstomping, and while the odd skilled dota player w/ new matchmaking rating may end up in there and do really well, I would hardly see it as a serious problem.
I know when I'm queuing on my own, I'd much rather run into an "even playing field" in terms of teamplay.
Am I alone here or is this something we should definitely have in DotA 2? I'm having a hard time coming up with downsides.
