@topic I've played MMOs with a mechanic that allows a group of/single player(s) to experience a dungeon on ez mode (like setting up the tier 10 lvls below yours, duo party manageable or the game assigns npc allies if you go solo etc) and its purpose is nothing more than a simulator or an interactive map. Nothing beats the experience of trying out the dungeon firsthand. I hope @OP you find a regular group to practice with/get wiped out with lol
