Thanks for all your comments. We know that AtlasLoot does not cover all that stuff it covered in older expansions.
The problem is, that none of the original authors is active any longer, or has time for maintaining the addon. We are glad that Proteyer currently seems to update AtlasLoot!!!
Complaining about missing content & features does not really help. It takes a huge amount of time to get all the content into AtlasLoot and it will take new contributors to achieve this.
