I'd like to propose that it's not Crafting that's killing itself -- it's Chests of Evil. Those CoE weapons are literally overshadowing everything else in the game, so much so that half of the balance discussions on the forums are essentially centered around them. It was OK back when seeing one CoE every 4 floors was a lucky find, but Dwarven Post Express rooms have completely shattered that, and made a CoE weapon a quite common find. Those weapons are so damn strong, I've had pure casters whose best option was to enter melee with their CoE Lirpa rather than stand back and cast -- and that's saying a lot. Either nerf the CoE weapon damage formula, or drop the Dwarven Post Express room's spawnrate significantly. Like make it only viable on floors 5, 10, and 15. Or something.
