[2020] Crafting Progression Item Drop Rates 6.200

For those of you actively playing 6.200 I am looking for feedback on the ease of which you think the various "souls" are obtained. This will be useful for tuning the 6.300 proc values of the crafting disciplines. I have heard feedback that feels like some of the professions proc too often and others not enough. Something like:
Armorsmithing - Felt reasonable, saw one every 10 pieces of armor.
Weaponsmithing - Felt too slow, saw one in 30 weapons.
Alchemy -
Runecrafting - Felt too fast, saw one every 5 tools, and tools are easy to make.
Necromancy -
Stonemasonry -
Jewelcrafting -
Leatherworking -
Woodworking -
