OK, that makes sense. The capitol and the first ring or two will benefit from the extra shields. I'm guessing towns that will be useful only for specialists you'd settle the hill, right? Re: attacks, don't you get barb swarmed about 1500-1000 BC or so? A stack of 24 horses? Or don't you play with cranked barbs? Seems to me I get hit about then 25% of the games, and unless I've grown to size 7 or built walls, its pretty tough to hold out against them.
