Nothing will ever be "complete" But we have the most truely collected nameds than anybody hands down. I guarantee that. Same for pathing and loot. Faction will never be great. but it's a lot better than it used to be.
As far as zones, sure. not complete. never claimed to be. When Luclin and pop rolls around though i promise it will be 1000000x better than the 5.7 alpha1 pile of mess
If you have ever tried searching for an item or npc in our db you'd realize just how complete it really is. Barring a few rare occasions, we have every npc recorded on hackersquest, which is a LOT, if not all. (Some, especially in velious are in the db but not set to spawn because they will need to be manually placed)
Kunark is the first expansion to have this level of named accuracy thanks to a conversion script of the HQ database. All future releases will include these npcs as well. So you are stabbing yourself in the foot to not use them imo. But to each his own.
