I support the idea, and am quite sure it will force people to role play a lot more.
But it's like saying to remove system chat, it can't be done. As far as my records go, they cannot change what Microsoft already made, they can only add more to it.
Else they would have made a 'local channel' in your chat window, remove system chat (or made it into a very long annoying command so people won't bother to spam in system chat), change NPC's voices where they won't address you as a Freelancer, ect. ect.
But some things can't be done, and I think this is one of them. (even though it would have been awesome)
