Does Horde PWN Alliance in PvP? A Baker's Dozen of Possible Reasons
But beyond the practice factor, the faction with fewer members also has a higher chance of the same members bumping into each other over and over again. This makes it easy to know who the good players are.
The reason Horde in general do so well as there are fewer of us so many of us have battled together before. We know who is good, how we play and can synchronize our fights. [WoW, F, 43]
Inside the Battlegrounds, you often get grouped with the same people or same groups of people as Horde, allowing you to learn each other's tactics better and know who to listen to, etc. On the Alliance, since there are so many people, I think that's harder. [WoW, M, 19]
This is particularly important for the emergence of known leaders in a situation where there is a very limited amount of organizational time.
This also means that the good leaders become *known*. When you only have a couple of hundred people who regularly play in the BG's on the Horde side you quickly learn who the good players are, who the good leaders are and so they get listened to. [EO, M, 36]
Facilitates Sustained Groups
One related point that should be highlighted is that the shorter BG queues also make it easier for PUGs to become sustained groups for the side which has shorter BG queues. On the Alliance side, queuing up as a group increases wait times, whereas this is not the case for the Horde. Thus, from an organizational standpoint, it makes more sense for a Horde PUG to stay grouped than it is for an Alliance PUG.
Because of insta-queue times, PuGs become 'groups' within a match or two. You leave and queue up again together. The mere fact that you don't have to waste the first 55 seconds of the raid trying to figure out who is going to start the group, how you are going to get invited, who's leader, etc. makes a huge difference. More than once I've just barely gotten in to the raid group and the horde are halfway across the field. However, on the Horde side, this isn't an issue. Moreover, once you are in a group for a few matches, someone can begin to emerge as a leader who can be trusted. Someone can emerge as a flag carrier. Someone emerges as a trustworthy healer. Working together eventually leads to you working together, if that makes any sense. [WoW, M, 27]
