Regular townies turning into spellcasters?

I don't want magic restricted in the magic realm. They need to be out in the world. Really, if you want to be realistic magic would not be restricted to one area . I don't understand people who stomp their feet and demand that (aliens, vampires and spellcasters) be restricted because it would interrupt their game play but what about those of us that expected that to happened but then again those are the ones that think they have to have it their way and who cares about anyone else. If I didn't want them in my play then I wouldn't buy them I sure in the world wouldn't have a fit and demand them to be restricted because I think my play is more important than the ones that actually want to play the way it should have been.
