First, your posts throughout the thread aren't of a different tone or inclination than the ones earlier on, so I could have quoted any for my response. Save your indignation for when its warranted.
Second, your example isn't even remotely related. Not only is it an example of something completely unnecessary, but it does nothing to support your point--that enacting one change would enable others--since they didn't enact it, so you have no clue as to whether doing so would have had any bearing upon possible future such additions.
We're not talking about making some change to the game to facilitate role-playing, or dumbing the game down for everyone, nor about catering to every shmo who has a handicap, as many cannot be addressed in this context. We're talking about a fairly simple change, and one which (apparently) other MMOs do feature. It does nothing to detract from the gameplay of anyone else.
