Another problem (if you consider it one), most people while calling for a pseudo-medieveal base have no idea what medieval even means.
Most off what people think as medieval is either a complete entertainment industry invention or at best very late medieveal era, but more often than not rennaisance era.
The stereotypical knight (paladin) in armor? Not medieval. Medieval knights did not wear plate armor, ect.
If D&D and FR were really to use the medieval era as base it would look totally different from how it does now.
