Well it will be a pain to re-cast magic reflect and reactive armor.
But I think it's great if people can no longer stone-on Inscription, cast MR / RA, then stone-off Inscription and keep the +5 resists bonus.
the +5 elemental resists have nothing to do with incription.
All inscription did was make it to where, at GM inscription, the Reactive Armor Physical bonus, and the Magic Reflect Physical penalty, offset each other.
At 0 inscription, you can STILL cast the two spells, and end up with a net gain of +5 in each; those are the BASE MODS of those spells, regardless of inscription. What you don't get is a net 0 change in physical (you end up at -20 physical, -16 if human).
So, recasting them from scroll (which a human can do), only requires that you "overbuild" your suit in PHysical resist (which is easy enough to do with spined or barbed leather)
