The biggest thing I'd like to see is a change in dialogue where evil is always this violent "fuck you" kind of person.
You can absolutely be a pleasant individual and by wholly evil.
Hannibal Lecter, for example. "I find discourteousy to be unspeakable ugly."
Jon Irenucus was absolutely evil, and a complete bastard, but he also wasn't just a "fuck you rawr violence!" evil either. He was cold, calculating, and probably really good at dinner conversation.
The issue with alignment has ALWAYS been with writing and portrayal in media, and not with the mechanics of the system.
