Let's just say that my group, having played Descent almost weekly for the last year and half, has gotten very good at finding and maximizing roles on both the hero and overlord side.
After a break of a month or so, we'll be starting up another campaign, and looking for a new challenge, I've thought about using a sub-optimal hero. That also got me thinking about sub-optimal overlord decks too.
So, let's hear it, what do you think are the worst heroes and classes, alone or in combination? What are the merely sub-optimal heroes that are "almost there" but that you can find better options for?
