I struggled with a rogue on PoTD, as she died in the first few seconds of every combat (dual wielding, using a 'cautious build type') , almost gave up on the entire class, but then decided to go with a build using medium armour (the golden breast plate found in the Endless paths) a axe (Hearth Hatchet) and a small shield, cautious attack and weapon and shield etc and she has around 80 deflection (at level 5), does reasonable damage and more importantly stays alive to contribute to the group.
