First off, I really like the approach to crafting in Last Epoch. I think it adds a really unique layer to the game, BUT.
Drop Rates:
Glyph of Stability and of the Guardian are insanely low. I would expect them to help ALOT More for the rarity of them dropping. I get one of each per ~10 runs of a monolith.
Fracturing 100% chance @ 80% success rate:
As stated, I find I have a close to 100% chance to facture when I drop to or below 80% using a Glyph of Stability. Glyph of the Guardian doesn’t seem to work. Items don’t drop a tier, the item just breaks. Coupled with an insanely low drop rate… why use it?
Rune’s:
Rune of Shattering: Buy only? I have never seen these drop. The shopkeeper doesn’t refresh inventory until you log-out-in either, and there seems to be a time limit to that as well in that you can’t just log-in-out and re-buy. She also doesn’t refresh after time when playing either. Not that big of a deal as affix shards drop like crazy.
Rune of Removal: Always removes the first affix, top-2-bottom, not random.
Crafting a White:
Now, this is where I feel there is a major issue. Starting from a perfectly rolled white item. I have about a 75% chance to fracture BEFORE I can get 4 affixes on it. Glyph Usage helps here, but they are so freaking rare that I can’t get 4x T1 on an item due to lack of Glyphs. From this point, getting to T2 or T3 for all four is just impossible. This can’t be intentional as this seems like a core component of the crafting system.
Fractures:
I have never seen a Damaging or Destructive Fracture. Do they still exist? Is this why Glyph of Guardian doen’t seem help at all?
Summary:
It seems the best odds of crafting ANYTHING is to have an item with 4 affixes on it you want, and high level, then taking one up one or two tiers. Or 3 affixes and adding +4 + Leveling one. Pushing to T5 from a T4 will facture the item almost always, even if you have never crafted on it, which is crazy.
The stability numbers does’t really make sense as you can break an item with a low stability value VERY easily. E.G. 80% to work = damn near 100% chance to fracture.

Found a large number of other posts with the same feedback, mainly this very long thread.
