I would like Pazio to make an official ruleing that Fighter Weapons training meets the prereqs for the weapons Focus weapons specialzation line of feats.
First off it’s extremely unlikely paizo will make an errata based on the demand of a random forum post, particularly to something that has been in the Core rule book for how many years now? 12?
Secondly, why do you demand such a change? It’s rare for classes outside the Fighter to get weapon training and those that do have better feats to take than weapon specialization. And fighters already get plenty of feats that they can spare one for the prereq to weapon specialization. Besides, weapon focus is a decent feat that opens the door to a number of other feat chains that isn’t specialization.
