Well no, coming from someone who actually does exploit, the case of premade syncing isn’t exploitative in nature. Exploiting is typically referred to as abusing an unintended game mechanic (a bug).
Even when oQueue addon was around, that itself wasn’t exploiting because WoW’s API allowed an addon to do what it did. It streamlined premade syncing by allowing them to queue at the exact same time, and would decline a queue pop if that queue didn’t pop at the exact same time for everyone.
Blizzard didn’t like this, and they broke the API functionality for the addon so that this wouldn’t be possible. They didn’t suspend or ban anyone for it though because their design allowed that addon to do that. It wasn’t an unintended use of the API, it just wasn’t a possibility they had thought of.
Manual premade syncing is similar. It’s a result of how the queue system is designed. You queue for something, and the system randomly pulls in players also queued for the same thing. If people are queueing at the same time, there’s possibility that they can end up in the same game. Sure, people are making this more than a possibility by dropping queue whenever they don’t get the same pop, but the game allows them to drop the queue.
Is premade syncing unfair? Yes, it is. I’m not arguing against that. It’s just the unfortunate design of this system.
It doesn’t punish you for purposely dropping a queue over and over again, and even though players are manually saying, “queue at the same time / queue pop! / drop the queue!” they aren’t abusing an unintended game mechanic.
You can say, “it isn’t for you” all you want, but theres no argument that you or anyone can make that can’t deny that a premade vs a pug is unfair. A premade has the inherent advantage because you can choose people with gear over those with less gear, can choose class/spec composition in your groups, etc. compared to a team that has random variables.
It also doesn’t help that only one faction can easily premade sync and the other can’t.
Well that’s the beauty of cross faction random battlegrounds.
There would be no premade support. If you have to fight half of your group, it’s all the more interesting.
