Whilst I personally think the chest generation with dungeon crawl is okay enough on it's own, I think there could be a lot more variety with how chest loot is generated that could make exploring dungeons for loot more rewarding and more enjoyable.

I'd like to propose an idea that the dungeons from the mod could use various other chest loot pools to mix up what one could find in a dungeons; Maybe have it to where dungeon, desert temple and mineshaft loot can generate together in the dungeon's first four or so floors, with certain loot pools being more common to encounter the farther you go down; Maybe even have it to where certain loot pools like the ones for buried treasure, shipwrecks and woodland mansions have a rare chance to generate; Maybe have it to where bastion loot can generate in the nether floor rarely. I think that there's a lot of potential that can come out of Dungeon Crawl taking advantage of Minecraft's other chest loot pools, it could even potentially lead into the creation of new rooms, new secret rooms, and maybe even entirely new dungeon variants as well. Using other chest loot tables could also be fairly beneficial with making Dungeon Crawl more compatible with other mods that already use Minecraft's chest loot, adding just that extra bit of diversity of what you might find in a dungeon.
