BC being where all the classic players are leaves us with dead classic era servers. Do you think making only the classic era version of the game free to play would be a good idea? BC then becomes f2p after WoTLK is released and so on. Money lost to no subs would be gained via faster xp gain buffs sold with real money and other QoL as part of the in-game store. To enable players to quickly reach end game and do what ultimately everyone wants to do in multiple WoW versions: raid and PvP, they would be paying real money to get boosted on multiple WoW versions which would make more money for blizzard than via just subs plus the subs from retail.
