I definitely do not miss hunting down golems. What a waste of time and food that quest was. Especially when you sometimes didn't get the imp until floor 19. You had to waste a ton of time waiting for the needed enemies to even spawn.
The new vault quest is superb. I've only died once, and that was to like a 38 damage boss hit I wasn't expecting, and for some dumb reason I was hoarding my health potions.
I love waiting to start the quest until I'm starving and low on health because it gives you a full heal and full satiety when you do.
The friendly ghost quest is different. You kill one enemy and it spawns as soon as you start the quest. Rotating the enemy keeps it fresh. But hunting down monks or golems is so boring compared to the vault. Asking to have that back is like asking to have the old gold-mining quest back in rotation with the modern cave quest.
