Nothing unexpected there at all indeed. Considering the double (or even triple?) gating of Ironworks weapon... weeks to get the tomestones and then having to have SCoB cleared and then running FCoB for a 1/8 chance of an encrypted tomestone... it will be more than a month before we see these spread and people running around with them. Indeed, is it all so surprising at all? Nexus - previous patch, Ironworks - current patch. At least it could have been expected.

On the other hand though, the grind all the way to Nexus is not really in proportion to the reward at all, indeed. Best example of that is still the atma part of it.
