In different game genres there are features that, once they appear in one game, quickly become a staple of that genre. For example, WASD + Mouse in first person shooters or alternative fire in the same genre. Unfortunately not all features which should spread like wildfire, do.

This is a first in a series of posting about MMO features that have shown up in one game, should be in all games but are not.
