Is it wrong to be a Dark Lord in the dungeon?

It’s alright, I loved the concept of it. I mean Sauronin danmachi is a really cool idea. Ofc he’s extremely weakened he’s also born as an elf and joins Hestia and its follows the plot a lot. Also for some reason Lilly joins as a supporter which is dumb as annatar is already picking up the monster stones and drop as he uses the stones to make a ring, and it just doesn’t make sense why they would want her, as all supporters do is Cary weapons and items to use and pick up the stones and drops. The only thing that moves away from the original story is going to a mines and kill monster, they do this and they discover a flaming Minator and he uses his maiar soul and he kills it by banging his hammer into the blade that Hephaestus made for bell, but hestia didn’t ask for somthing for Annatar? Then they level up and they already know it before they go to get checked by there goddess. Which is not possible as you need to have them checked by the god/goddess to level up. But even if they did they can somehow read the language of the gods to know they leveled up. There are good things, the writing quality is very good and Thats amazing for WN.
