In 3.5 they did it like this (example):Archmage said:However, they probably should have left out the brief blurb in the class section that says armor and weapon allowances for each class count as the appropriate proficiency feats, or at least they should have emphasized that the prerequisites don't matter.
3.5 SRD said:If the ranger selects archery, he is treated as having the Rapid Shot feat, even if he does not have the normal prerequisites for that feat.-- http://www.d20srd.org/srd/classes/ranger.htm#combatStyle
So yes, a similar clarification would have been useful.
