I'm very excited for Legion overall. I think Blizzard has honestly learned from errors in previous expansions, and genuinely listened to players' feedback. The playstyle seems old-school, like Burning Crusade, or even Lich King. The talent tree system for the Artifact weapons reminds me of how it had been in vanilla. I do honestly believe Blizzard has learned from feedback, and listened to what the players want. I think this is the expansions that revives World of Warcraft.
