I am in a big alliance, that doesn't mean I have to like it or that I have to think this change would be good for the game/alliance server.
Yes, it's always been like it that bigger alliances can kill more and faster, the question is whether we should exacerbate it further (and keep walling just as impossible for small alliances while making it easier for big ones). I for one don't think so.
I agree with you that walling should mean something, I just don't think it should only mean something to the people in big alliances.
