Yes to getting white, black dyes and legendary repairs some way other than via a purge-specific thrall which only has a chance of spawning in specific zones … even IF they ever manage to fix the purge system (over six months now since our clan has had a purge despite being actively playing several days a week for a few hours at a time) … the possibility of getting those thralls is non-existent if you don’t have a base in particular areas.
I’m with Shadoza on that point … dedicated forges in a set location is not appealing.
Learning the recipe from inside a dungeon = yes.
Having to visit a set place and craft an item on forge / alter /whatever ONCE to learn the feat permanently = yes
Having to kill certain creatures to get items to craft recipes = yes …essentially forcing you to return to those areas multiple times to craft things … but we have to do that in this game anyways.
@pbcop82 put forward a suggestion that the legendary repair kits be added to dungeon boss loot tables to encourage people to go to them more frequently = yes …especially if on many bosses so you can pick one you enjoy fighting.
Or another player suggested into the loot possibilities of the world boss chests = though that locks out pre-lvl 60 from getting if they don’t have someone they trust who can open them for them.
