A run of disappointing expansions and ageing gameplay mechanics drove me away from Blizzard’s MMO, and into a nomadic search for something new, exciting and satisfyingly deep. But then, like a siren’s call, Warlords of Draenor tugged at me. Although I was deeply skeptical about returning, could WoW’s latest expansion turn me around?
