Clusters of Illusions
This particular observation:
The Orcish Mines never produces any really interesting (nonconsumable) items in its 4 guaranteed shops. You may find useful consumables but if you are looking for armor as a trog you will find Booksx2 + foods + random petty stuff. Or perhaps you are a spell caster, you will find platearmors and such (but not enchanted ones), weapons you are not trained in, foods, and maybe potions.
This used to not be the case in prior versions but I started noticing this as soon as I started playing v0.14+. It is my contention that shops (particularly in the Orcish Mines) have been nerfed without comment. Granted I haven't been playing as much lately and when I do I often splat before Orcish Mines but every character that makes it through O4 comes out with the same items they came in with. Aside from very rarely found items off of foes.
What is YOUR cluster of illusions? (Or what is your most recent one.)
