I would love that you don’t just do this for the APG classes but also for the other classes. I could mention Priests as one class with very few class specific feats. I will remind you that not all play a Priest as a healing machine wearing plate armor; a shield and mace... some actually play them as casters or combat buffers.
The amount of feats that are meant for martial classes are so vast compared to what is available for classes like druids and priests.
Where are all the feats specific for feral druids that want to focus a lot on their shape shifting? With the introduction of APG there are almost more feats affecting how to use a crossbow than feats the specifically enhance/alter abilities of druids and priest.
It might not come as a surprise that I am not very impressed on than additions APG gave to priests compared to other old classes.
So create these for the original classes too.
