Interestingly, although I've never played it myself I'm given to understand that in the buffy rpg that a Xander character is a full and valuable member of a party who can have as much fun as the slayer or other PC's.
Perhaps something d&d can learn from that?

I have said in another thread that roles seemed to be the alignment of 4e: it's as if "You can't do that, you're [role]" killed "You can't do that, you're [alignment]" and took its stuff.Ironically, I remember early in the life of 4e reading the point being made strongly by WotC that the design was supposed to make sure that 'whatever you chose to do with a class, it would still be good at its primary role' - which over time somehow morphed in peoples perceptions to 'your class is mechanically locked into a role'.
Now, it may or may not be that designers after the initial design didn't grok that and ended up introducing stuff which had the effect of locking people into a role. I don't know enough to judge - but it wouldn't be the first time that original design principles got undermined, and it won't be the last either!
