World of Warcraft has always had an imbalance of players who choose to pick the strongest faction, and the issue only grows as more and more guilds begin to migrate over to the Horde side.
This isn't only an issue for raiding guilds, as the game is an MMO, people need others to play with, and if everyone sticks to the one faction, there is less of an incentive to move to the less populated one.
The topic has been rising within the community recently and Game Director Ion Hazzikistas even commented about the issue on Twitter.
Will World Of Warcraft Ever Get Cross-Faction Gameplay?
Ion says that "there is no quick solution" to the issue and he acknowledges that there is a problem that needs to be addressed.
The Horde Hall of Fame closed three weeks ago, and yet only 65 alliance guilds have managed to defeat Sylvanas on Mythic difficulty.
The Oceanic region is the only exception, as they are Alliance dominated, but they are a small minority in the main scope of the game.
Not only does it affect the high end, but this behavior trickles down into casual play, causing the majority of players to pick the dominant faction if they want people to play with.
The old excuse was Horde's racial abilities are just better, but that is no longer the case and many will argue that the Alliance is in fact stronger today.
Cross-faction gameplay goes against the design of World of "War" craft and Blizzard is in a tight spot no matter what they decide to do in the future.
Things like the removal of PvP servers, and mercenary mode for battlegrounds diminishes the argument that there cant be some sort of cross-faction gameplay in the future "lore-wise" or because of gameplay restrictions.
Whatever Blizzard chooses to do, both sides will have to compromise in order to preserve the health of the future of World of Warcraft.
