I prefer Dynamic queue over Solo queue
I've never had a single problem with Dynamic queue. I've never felt it was unfair, I've only enjoyed being able to play with old friends and make new friends along the way. I've been the single in 4-man premades before and they have never once flamed me or singled me out for abuse. If you ask me, people are only complaining about this because they have no friends to enjoy it with and just want to come up with any excuse possible why they aren't challenjour.
