You know pve has an endgame, and so does pvp (eventually), but what about DoH and DoL, where's our raid gear, and why do we have to do pve dungeons to get mats?
What if there was a raid for crafters say with 4-6 large scale projects that required one of each DoH and DoL. How it would proceed each NPC guildmaster will hand each DoH and DoL a work order with 3-8 different objects to create or gather depending on class(key items that disappear upon leaving the raid) The work order will contain all the recipes required for each project and disappears upon completion of the project (same as the key items for each project)
Now each DoL will support the DoH in gathering the mats say for instance:
Fishing would support Cooking, Alchemy, and Leatherworking
Mining would support Blacksmith, Armorsmith, and Goldsmith
Botany would support Weaver, Carpenter, and Cooking
