Suggestions for Flexible PrE Feat Requirements
Please consider allowing more build creativity by allowing thematically appropriate substitutions to qualify for PrEs. A great example of this already exists. Arcane archers can take past life: sorcerer instead of mental toughness. Perhaps very few characters take advantage of this, but for those that do, it can add more depth to their goals and character.
More flexibility, without dramatically changing the power of the characters, lets classes be more customizable.
Most of my suggestions relate to past lives, but even expanding the current list to otherwise underused feats would achieve this goal.
Shintao monk I
Past life: Paladin (or possibly monk) substitute for Combat Expertise/Diehard
Ninja Spy I
Past life: Rogue substitute for Dodge
Archmage I
Past Life: Sorcerer instead of Mental Toughness
Defender of Siberys I (possibly Stalwart Defender)
Past Life: Fighter instead of Tower Shield Mastery
Frenzied Berzerker I
Past life: Barbarian instead of Cleave
Warchanter I
Past life: fighter, past life: barbarian, or skill focus: intimidate instead of weapon focus
Virtuoso I
Past life: bard instead of skill focus: perform
Spellsinger I
Past life: sorcerer or wizard instead of metamagic
Assassin I
Past life: rogue instead of Rogue Hide II and Rogue Move Silently II
