It can only be determined by the person conceiving the character concept. Nothing irked me more than being told by people that X class fulfills my concept, so I don't need Y class to be made. They had no ability to determine that for me.How do you determine what concepts require classes and which ones can be handled via feats?
What I'm saying is that you can achieve or partially achieve a concept through taking a feat(as determined by the player), but you cannot achieve a class or subclass by taking a feat. A class or subclass requires an actual class or subclass.
