right but what i mentioned in my previous posts this is unlikely to happen. the normal rules seem to assume the bestary feats are available so there is no need for another book to say "these feats are available to eidolon". this was different from ac because ac are int 1 or 2 normally. so ac needed their normally available feats spelled out.
really as far as pfs goes its likely the fact that eidlon cannot take beastiary feats is probably deliberate. as id said earlier it prevents alot of power issues with eidolon.
limiting what a player/their class granted "pet" can get for the sake of being "fair" is stupid (although i do understand why it was done) and should not be part of the game rules. this is a decision that only the DM and party members as a group should decide, not the rules of the game.
if everyone in the group wants to be a combo of vampires, graveknights, and liches, then so be it as long as everyone agrees. this shouldn't be stopped because the rules say a player cant have an acquired template.
