For further visibility, let’s put in here exactly what is in the article, which is Blizzard’s (Daxxarri was a WoW CM back then) view on the matter back then, and should be the PoV of anyone with a modicum of common sense:
Any addon that enables a full, organized Battleground group to queue against a randomly assembled group is creating a scenario where that coordinated group has a huge advantage. That is not in the spirit of the experience we want to provide in the normal Battleground queue. Playing with friends is fun and important, but it shouldn’t come at the expense of the spirit of the game nor the fun of others.
The normal Battleground queue is for players to jump in and play against other players in a similar situation. We realize that it’s not a perfect system, and we’re still looking at ways to improve normal Battleground queues further. Regardless, it’s not meant for organized groups to “pug stomp” and get quick Honor. We have built in outlets for players that want to organize–if a competitive, social experience was really the goal, then there are clear ways to achieve that.
The ultimate effect that this kind of queuing has had is to drive players away from PvP. Perhaps it’s been a long time since you’ve been in a random group, but a lot of players will see that they’re up against a premade and simply quit. At best, they suffer through it. To an extent premade groups count on this. Heck, one of the popular addons announces opposing players that appear to have rage quit.
