I can live with it. I don't have to like it, do I? It's much less complicated than adding ReVi and Penetration to the mix, which was my big huge concern. It's going to give even the mightiest magus pause to declare Wizard's War, because holing up in the Wizard's Tower becomes a very real and valid defense strategy. Only those with massive forms resistances are going to try and come through the Aegis.
