LFG Heroic: The Halls of Simon Kaine
For the most part, I'm pretty happy with how the system is currently.
Having a class system would be incredibly clunky and problematic given the nearly endless possible choices simply for basic character concepts. If we were going to do anything akin to it, I'd recommend we do something along that SW Rebellion did with its heros.
There are four attributes: Diplomacy, Leadership, Combat, Esponiage.
Give a character a hundred points to spend total on those attributes. And if, IF there is a conflict between opposing PCs that is having issues being resolved OOC, the character with the higher points in the related area wins. Hence, there is still a fair amount of flexibility with what characters can do, but the core concept of what that character can do is protected.
My main concern that I've had is characters that can seemingly do everything just as well, even sometimes better, than a specialist character (regardless of it's PC or NPC).
