Under "Advanced Rogue Talents" it lists "Feat" as an option. Can Rogues only take a Feat in place of an advanced Rogue talent, or any rogue talent? While it is listed under the advanced section it simply reads:
Feat: A rogue may gain any feat that she qualifies for in place of a rogue talent.
Second tier of this question:
While you can only take any rogue talent once, can you take a feat instead of a rogue talent multiple times, since you are not technically taking a rogue talent?
Advanced talents are taken as a rogue talent, you are just getting more, and stronger, options.
Second tier: No, it is a talent that gives you a feat, just like combat trick.
