Honestly, the worst type of ranged enemies for naked dudes in standard conditions are throwers with light projectiles such as stones. But considering how rare those are, and that they usually won't kill you before you locate them, archers and crossbowmen are worse in practice. Between fighting Phyrex and commiting to a ladder during an attack, I'd sooner fight Phyrex.
You forgot a class: Naked.
The hero?
... probably Kafein.
Thanks bud, wanna join my clan ? We got the best banner ever, and a couple of looms available in the armory (not the kind that will probably interest you though)
Also
if I'm naked hero number one, you are most probably number two. Not many people are 24/7 naked.
