My immediate response is "make Premium and Premium + more attractive". Monthly subscriptions are a huge source of revenue- look at what happened to Blizzard when WoW came out. The discounts that land barons got here should also apply to Premium or Premium + residents at least. Homesteads should have been reduced just like full regions. The whole point of moving to AWS was to be able to roll out regions and homesteads faster, easier, and cheaper. They should be taking advantage of that.
