Please remove the zombies from fab dungeon and add bandits in their place, you can currently run past all of the zombies in the tower to get down to the boss. It's more challenging in Haven than the real world. Please fix
I also feel like zombies outside of Haven should be the same as zombie in Haven. Zombies outside are harder to kill and basically offer the same reward besides some random junk
If they're going for the same theme they were in MO1 of it being a Necromancer's Lair, then it'd make sense that there are undead. If anything, after the necromancy update drops they should beef up the mobs there with various types of undead and make it more terrifying/difficult the deeper you go.
