Is this really such an interesting (and original) insight? I applaud Aniforani (the OP) for spelling it out here. But if the Dev. team isn't already thinking in these terms, then we collectively overestimate their worth.
I really hope this is not a fresh thought, that had to be relayed to them, by you, from the player base, but one (and a pretty basic one, at that) of many paradigms that they are constantly formulating to create depth in their (and our) game universe.
