If it weren't for the DOS-influenced combat the origin characters would be the most hated feature for me. I don't like them. I really don't like what influences it had on the development of the game and I most likely because of all that won't use them even as companions.
All the effort put in those GM created characters should have been spent on the player character and improving their experience. Companions should be designed as NPCs and good as NPCs, not player characters.
