Pazu said:rgard, I understand what you're saying, but that wasn't really my original point. As has been pointed out, it's relatively trivial to kludge a sorcerer (or any other spontaneous arcane caster) into this class--heck, as I said in my OP, a vanilla bard can take it without any additional feats or PrCs!
All you need to do then is reduce the Knowledge Planes ranks requirement. Nobody has posted that there is official errata for this, so just do it yourself.
You can also ask Wizards or use the Sage advice tool there. Maybe you'll get your answer that way if you don't want to HR it.
Thanks,
