Uncut Spirit Gem-Droprate WAY TOO LOW

tl;dr make the odds of dropping Uncut Spirit Gems occur once in 2 completly cleared maps. let go off once in 50 maps

im currently looking for a Uncut Spirit Gem, and im pretty annoyed by the low drop rate.
i cleared 'The Bone Pits' for 35x by now and i didn't see a single one.

what does that mean:
• mistakes by casual players are inexcuseable. casual players are forced to replay a buildguide, rather to explore the game on their own.

• players are more likely dependend on aviable guides to play the game.

• ingraving an Uncut spirit Gem by mistake to a wrong one, brick the gameplay for dozen of hours

• 65 Uncut Skill Gems don't make up a single Uncut Spirit Gem.

• gem progress is stalling and non existent

• market prizes for Uncut Spirit Gems inflate just by this post

• GGG devs are out of touch or dcaf, since the low droprate was already a community noted issue in 0.1
