One day later I've already got ideas on how I'd houserule games I run with this system.
All Classes
Attack of Opportunity is a Bonus Feat for all. It is gained at 1st level
Alchemist
Alchemists are mostly changed by the house rules on alchemical items
Barbarian
Superstitious now only applies against Arcane and Occult magic for the purposes of anathema and class features.
Bard
Bards are unchanged
Cleric
Clerics are Unchanged
Druid
Wild Order Druids gain Form Control as a bonus feat at 1st level. The feat itself is now a level 6 feat.
Fighter
Fighters get an additional bonus feat (of up to 2nd level) to compensate for everyone having Attack of Opportunity
Monk
Monks get Monastic Weaponry as a bonus feat at 1st level
Paladin
Paladins gain Sense Evil as a bonus feat at 1st level.
Ranger
Rangers can select Fighter Bonus Feats as if they have a fighter level equal to their current level-4 (minimum 1). Hunt Target also applies Forceful to weapons (and stacks with Forceful if the weapon already had forceful)
Rogue
Rogues are unchanged.
Sorcerer
Sorcerers are unchanged.
Wizard
Quick Preparations costs 1 spell point to use, and grants +1 spell point.
Archetypes
Archetypes can be selected as general feats in addition to class feats. Multiclass feats do not interfere with other archetypes
Resonance
Items with the Consumable Trait consume a resonance point when crafted of they would require Resonance to be used. Any resonance use with the item after the initial consumption uses resonance as normal. The Infused Trait applies to temporarily crafted alchemical items.
Probably more to come, but that's what I've got.
