Fifteen years of iterative design means that the World of Warcraft that existed in 2006 is dissimilar to World of Warcraft: Battle for Azeroth as it exists in 2019, even if you’re playing the same content. The cumulative effect of thousands of tweaks means that pinpointing exactly what made Classic so special is a nebulous undertaking. Flying mounts, for instance, were a welcome addition when they were introduced in The Burning Crusade. It eventually became clear to players, however, that the convenience and fantasy they offered came along with a number of significant drawbacks like reduced interaction with topography, enemy NPCs, and other players. In spite of this, flying limitations are met generally with negative feedback on the part of BFA’s community. Such conveniences are difficult to unlearn.
":" - Any time a step ends in a ":" instead of a "." means that the next step is part of the current step you are on.

I had the privilege of traveling to Irvine, California to play before the beta started and talk to the folks at Blizzard behind the project. They told a story of learning, enthusiasm, and cautious optimism in regards to WoW Classic, perhaps best articulated by J. Allen Brack, the recently appointed President of Blizzard Entertainment. He’s a thirteen-year Blizzard veteran who, until recently, had been with the WoW team since vanilla.
