It makes me really sad that they are including Battlegrounds in WoW classic. There was a magical period from release date to the first Battlegrounds patch where people actually took part in large scale, world PVP. Guilds would get together and raid towns, and it was the most fun I’ve ever had in an MMO. If you wanted to do something, it took lots of planning and working together with people, not just clicking a queue…
This is the entire reason battlegrounds were introduced - balanced world PVP was unviable on almost every server. It was one of the primary complaints about the game, and could even have resulted in the loss of the PVP orientated player entirely if it had not been addressed.
