nerfed yes but feat chains are a useful tool not provided by "you must be this tall to ride" type level based feats. Not just anyone should be able to take more advanced feats just because they happen to be level x.This seems a good example of a feat that should simply be nerfed....or again given a scaling mechanic so that by the time it hits its godly power its at a tier where that power is just par for the course.
That is much simpler than introducing a feat chain to try and balance it.
