Raiding on Green and Teal will make raiding on Blue look like child's play. The top guild will ruthlessly crush everyone else and most people will not get an epic within these servers' fully-known timeline. Even without taking raiding into consideration, the competition for legacy items such as Manastones, Guises, and Thex Daggers has in just a few weeks demonstrated that the magic of classic Everquest can never be fully recreated. This is through no fault of the Project's devs, but rather due to the age of the game and circumstances of the project in its decade-long existence. The anticlimax of Green and Teal will hit and it will hit hard.
This isn't 1999 and it never will be again. This isn't 2009 and it never will be again.
