- No flying mounts = So nostalgia over no flying
- No shop = So anger over something that has no effect in-game
- World PvP in every zone of the game = I played in Vanilla, outside of random ganking which still occurs now, "World PvP" generally was in a few select zones
- A real raid system with progression, not just the same raid over and over again = Until you beat Ragnaros and have to just farm him on the same difficulty
- A real economy = Trading goods for gold hasn't changed in 12 years of WoW
- Bots and cheaters get banned = They do in Retail it's just the population and spread of servers is much larger
- A talent tree system that actually gives you a sense of progression = Cookie cutter builds and +% to x Ability isn't really progression
- Cities filled with players = My servers Cities are still filled with players.
Your private server sure sounds appetizing
