Are there any in-game clues for antiquity leads? Like there are for museum pieces and skyshards? I don't want to google where to find particular leads because I have always enjoyed finding museum pieces and skyshards on my own. But if there are literally no clues whatsoever for where to find leads and we are just flying blind, that is lame.
Or is there a method to the madness? Like, "every zone has a lead from harvesting," or "every zone has a lead from fishing," or "every 4-man dungeon has a lead", etc. I mean, I don't want to spend weeks clearing every delve in the game just to find out, "Oh, there is only one lead from a delve, and it is a 1% drop chance from a single boss in a single delve in Shadowfen."
I don't want leads handed to me on a platter, but I also don't want them to be a complete and utter mystery.
