I gave the craft reserve and item creation feats so they wouldn't just be wizard with infusions and leftover experiance that is only fir for potions.
Not arguing with that, it's a very good idea. What I mean is you've allowed them to continue gaining the Artificer bonus feats granted by level progression, but you've also listed 2 levels on this PrC where you gain a bonus feat. That makes for quite a few feats if I understand correctly.
