That's not quite what I was getting at, sorry if I phrased it badly. Favored Soul here gets a bonus feat at 3 that's meant to be Weapon Focus in whatever weapon your deity favors (as the in-game text box describing the class says, you are required to put the bonus feat at level 3 into that). It's possible, or rather likely, that your deity favors a martial or exotic weapon, meaning in order to fulfill that requirement you have to take as your level 1 or level 3 general feat the appropriate weapon proficiency to be able to use the weapon to then take weapon focus in.
If it's instead supposed to be a situation where it's just a suggestion and not a requirement that you take WF in the favored weapon, then the class description in-game should be amended to say that.
