Severe lack and overuse

I'm in a slight rush, so I'll make this quick as I can, and as clear as possible.

In the past, many a rare item had but one use, maybe 2.

Currently, items such as Gabbrath Horns, are the ONLY viable method of skilling up MULTIPLE crafts.

They are the only semi-readily available crafting item to cap smithing.
They are also the only semi-readily available crafting item to cap Bonecraft.
Also they are the the only semi-readily available crafting item to cap Woodworking.

This leads to a SEVERE shortage of supply, as 3 of the crafts are all competing for a singular item...

I cannot recall a time in the past where a scenario like this existed, Divine logs were for WoodWorking ONLY.

Shining Cloths were for Clothcrafting ONLY.
Venomous Claws were for Bonework ONLY.
Damascous Ingots for Smithing ONLY.
Etc etc etc etc...

(now my recollection my not be 100% clear, there may have been other uses for said items, I'm reasonably sure there were not however).

So, in making the Gabbrath Horns the only way(reasonable) to obtain skill ups via FIVE items Across THREE disciplines... is a sizable mistake, do you not agree?

Also, there is a mistake in it's naming, more of a minor annoyance;

Typically something so rare has a specific name such as Tojil's Horn, as if to state that it can only be obtained from killing that specific enemy.

Where as items like Ram's Horn, is obtained via multiple enemies...

Is there plans to add more Gabbrath's throughout the game? (And Rockfins, and Bztavians, etcetcetcetc.) Or atleast allow the Wildskeepers to also drop said items?

Here's a hint, if WKR enemies dropped Horns/meats/teeth/wings instead of pebbles, you may see an upswing in attendance, and if you tie drop rate to colonization rate, it may infact cause the players to have a reason to obtain 100% rates, instead of Quick Drawing everything to death at a Snails pace.

I mean, if I'm wrong, I'm wrong, just venting and my 2 cents etc.
