It seems that HELM is pretty much dead and SE has realized this by making HELM results drop in other ways. A simple solution is to add results in all areas that are Exclusive and add new synths that have HQ results (or higher HQ results for synths that already have them) that use new Exclusive HELM results.
Example in Mining since I know Smithing best:
Add a Large Adaman Ore (Ex) in areas that already have Adaman Ores and maybe others also. A new Adaman Ingot synth is added using new Large Adaman Ore where synth results are NQ 2 ingots, HQ results of even more Ingots.
It would also be nice if all new base crafting materials that should be HELM results but aren't were added to existing / new areas. This also gets crafters out and collecting materials as they should be.
Thoughts?
