1.) Server Populations: With servers being funneled into fewer zones, will layering be coming back? Will dynamic respawns be a thing to support the resource requirements of larger servers?
2.) Faction Imbalance: What is being done to combat this? Faction specific queues, faction locked server transfers, merging servers, etc?
3.) Botting: How is Blizzard going to be better at detecting and preventing bots?
