None of this karma stuff seems in the spirit of Superman. People like Julian getting picked on is the best reason in the world to ditch karma. Sure, he's obsessive (or at least, he seems to make time to be obsessive) and I don't always agree with his ideas, but he brings new ideas and discussions to the table and isn't a troll by any stretch. If I wanted cliques and cults of personality, I'd go somewhere else. I'm here to share with other people who have genuine "love" for Superman.
If anyone wants whatever little karma I have to apply toward a negative karma balance and make it a positive, I'd love to somehow give mine away like a penny jar at a cash register. On that note, the karma thing might be more compelling is if karma points could be used for harmless fun that actually relates to the board itself. Perhaps there could be a gambling pool on who Superman's next writer is gonna be, or when Lana stops being CEO of Lexcorp? I dunno.
And besides, "karma" is a Marvel Super Heroes RPG concept, not DC.
