Wizards of the Coast has been asking the public for feedback on various aspects of the latest version of Dungeons & Dragons. In their latest survey they're asking about settings that people would like to see updated to 5th editions as well as what classes and races they'd like to see.
Dark Sun fans, this is a great opportunity for us to make our voice heard. Make sure to select Dark Sun in the settings section. For the classes section there are no psionic classes. For the races, be sure to select Half-Giant and Thri-Kreen. There is a box for open text you can include your own comments. That'd be a great place to add the psionic classes (Psion, PsyBlade, Psychic Warrior, Ardent) and perhaps the Mul race.
