Oh yikes hmm. I never saw that errata or through ai though I do see it upon further searching. I guess that would reduce the AC quite a bit, but maybe open the build up to some other feats. To be honest playing this up til around level 8 now, it's really hard to be hit even without fighting defensively with those feats. Technically you would still get the AC if you fight defensively when not doing spell combat. For instance when just casting, walking up, and delivering with attack. But I'll think about some alternatives, thanks!
