My point is servers/games like Delteria are at their core, designed for recycling. If Classic was in the same position as Delteria we could easily churn out entire new towns, quests and dungeons with little effort. All that "customization" would be the equivalent of new items that could be put as loot. All the morphs and mounts would be the same amount of effort as creating a new baddy.

But Classic is not designed for recycling, and that's the problem. We can't create a string of rooms, fill them with newly skinned baddies that use the same AI, and drop the same items but with better stats and call it new content. Sure, a baddy on Zodiac may have a new ability that another baddy doesn't have but that's very simple to add, especially if it's something like a spell that players already use. Adding a new ability is not the same as creating new AI and behavior.
