Eric was a cavalier, not a paladin. For the other characters: Diana was an acrobat, Sheila was the thief, Presto the wizard and Hank the ranger.Eric always was referred to as the paladin. But "who is the audience?" is always a problem with animated revivals. Do you aim it at 12 years olds like the original, or the 40-somethings for whom it has nostalgia value? Very difficult to hit both targets.
If they do the D&D cartoon I would assume it would be a complete reboot, so it's own thing with the occasional Easter egg nod to the original show. Seems like it could work just fine, a lo of old cartoons such as Bugs Bunny had a lot of jokes that only adults really got but they were still primarily viewed by kids. Heck, I remember going to the Shrek movie and having some pre-teens in the row in front of us looking oddly at us because of some of the jokes that they just didn't get. It's not an either-or situation.
