I suppose most classes get the spellcasting automatically? but on Hierophant, at least, you have to pick it. There's no warning about that. What makes it problematic, is that it also offers you the metamagic feats (see spoiler below) that you might end up taking if you don't know because you might assume it's automatic class feature anyway. This will make everything go wonky on the next level. Not to mention being confusing because there was not supposed to be any feats on first level to begin with.

Just figuring out how the qualification feat comes up was a challenge. Had to relog after meeting the qualification criteria for it to actually appear. While other qualification feats appeared left and right.
