With Battle for Azeroth, Blizzard want to reignite World of Warcraft’s age-old conflict between Alliance and Horde. But this emphasis on hostility between the factions risks branding a significant portion of players as belonging to the losing side. That doesn’t seem healthy.
Throughout Legion we saw the barriers between factions break down. The Horde/Alliance split became almost arbitrary as, instead, class identity became the focus. It even made sense towards the end of the expansion’s storyline that we would band together to defeat an evil that was bigger than both Sylvanas and Anduin. Legion was about bringing everyone together.
