Anyway, the scarcity of stuff like Pamun and Sharur probably has more to do with the fact that few people play or gear NIN anymore, likewise DD WHM or Club DD PLD. RNG's niche lately is the Delve Bee, and for that event RNGs are still using Annihilators for lower enmity damage. Your Echidna's information may not be accurate anyway. In July, 8 Echidna's have been sold on the AH on my server alone since it relies on a Meeble Burrows mat. One is in a bazaar right now for 12M.
In the end, it doesn't matter how many of them exist. It only matters that people know about them as an alternative, and that they are at least obtainable with a modicum of effort. Which relates back to my earlier response to Demon. The boss mats are flooding the AH at 5M or under, so those aren't the problem. The only scarce materials are the Ormolu Ingots and Scarletite Ingots, and some of the synths don't require those (mostly the mage stuff like Balsam Staff and Atinian Staff).
Interestingly, AH.com reports something like ~300 Senbaak Nagans owned across all servers. That takes Scarletite Ingots, so obviously they ARE being generated with a degree of regularity. People are making the crafted weapons. They are just making particular ones, and it looks like it corresponds to the popularity of the respective job.
