Death to the Trinity! Off with their collective heads, right? Well, I think that the trinity is perfect for this game – not for every game, but for this one. I want players to be able not only to self-identify with their characters, but also for everyone to know what they are fighting when they look at their foes. If I was designing a single-player RPG, it would be a skill-based game with no classes, but for Camelot Unchained, I think this is the right decision.
