I agree with his solution to the problem(giving people deserter if they drop their queues). I don’t know if queue-dodging is to blame for most of the problems he mentioned.
The fundamental problem is that premades don’t want to fight against other premades. Even if they win it is a waste of time. There isn’t a culture of queue-dodging, there is a culture of doing whatever increases your honor-per-hour because there is zero benefit to playing a long game, regardless of if you win or lose.
As for the premade vs premade priority system, sure it killed all the premades on the weaker faction and made it easier for the bad premades on the stronger faction, but the real failure of the system was that it allowed premades to queue against pugs if there were no premades to queue against. Had premades been forced to play only against other premades, either the premades would always play against other premades, or there would be no premades(which is what would have happened).
I find it a bit ironic that he presents his case as if he has a genuine interest in the health of the PvP community, and for the casuals who are negatively-affected by queue-dodging.
If he was actually concerned about the health of the PvP community and for casuals, he would be opposed to premades altogether. Queue-dodging might worsen the symptoms but it isn’t the disease.
If it were up to me I would do both. Give people deserter if they drop their queues, and put premades in their own brackets. Every game would be a pug, but with a mix of noobs and pros. No game would be a beatdown, and the pugs could actually enjoy the game instead of getting rolled by premades over and over and over.
If they did force premades only against other premades, I would actually be fine if they gave premades some kind of bonus for going up against other premades(regardless of if they win or lose). Which possibly scales based on the quality of the team they’re going against(maybe based on a hidden elo?). Enough to make it worth it for them to queue, but not enough where it could be exploited.
