The most UNPOPULAR faction in Heroes 5.

I don't like the demons. Especially the design.

What exactly don't you like about the demons' design, when other factions' designs are fine? I think everything is done well, except perhaps the Cerberuses (they really are drawn rather roughly). The Devil, if you compare him to the demons in Heroes 3, has gotten quite a bit fatter, but he looks impressive and intimidating. :) :)
