Dazsos, following general T1 etiquette, what your shield would have would still not be a prep which means a prepped attack would overpower it, and a quick draw would match it, provided the choice of attack was not poor (ex: magic missile fired at antimagic barrier). I'm not really sure what you're trying to argue about the shields IC. That they're slightly more special than a quickdraw, but less than a full 'prep'?
