Why Dynamic Queue will never be competitive or balanced
Let's take a normal game that I recently played with 3 of my buddies: https://i.gyazo.com/4aff87d8db968ce9b7312fa513a28b43.png Green = Solo queue players Red = Enemy queued players Blue = Me & my buddies
Because we're queued as a quad, and we're against only a trio, they enemy team gets a MMR boost, they get a solo queued Vayne who's a division above the majority of our team. We're also given a player who's unranked, and was ranked Bronze last season, and they're given a low-elo player as well. Theoretically, this combination is somewhat fair, and I'm sure Riot's matchmaking assumed that both teams had an equal chance of winning.
However, there is one thing it doesn't keep track of: the importance of each role, and the importance of communication between the roles of the queued players. In our instance, our low-elo player is placed in the mid role, and has no communication with the rest of the team. While their low-elo player is placed in support, partnered with their highest-elo player, and is comparably less important to the queued players.
This game turned out to be a complete stomp, mid got ganked early, and preceded to die numerous times in a row due to lack of communication along with an obviously unbalanced skill match up. I was unable to be of much importance bot lane, and our ADC wasn't able to out-perform their high-elo ADC player, neutralizing the lane, along with many other mistakes that weren't match-making related.
Games like these are extremely demotivating, and the outcome never feels like an achievement. The value of a communication is not a calculable constant, and even if Riot is able to balance the win rate of dynamic queues and solo queued players, these games will not be enjoyable, or competitive in nature.
TL;DR: The optimal 50-50 win rate between solo queue players and dynamic queues will NEVER represent a fair & competitive game. A 50-50 win rate does not necessarily assume competitive in nature.
Note: I'm aware that this situation probably wouldn't occur in a ranked game, but I haven't been playing ranked recently so I don't have an example of this on hand. However, I assure you, this type of game occurs more often than not when a dynamic queue is involved.
