All are 3/4 BAB.
Every combination ends up with all good saves.
All end up with decent skills.
ZAM/anything is already broke beyond the need to explain...
The Inquisitor/Psychic Warrior combination gives the Inquisitor a huge boost with bonus feats, and another pool of resources...
Thoughts on the best action economy or anything that I might be overlooking?
All have their own strengths, but something like the ZAM/Psychic Warrior has multiple abilities, pools, and bonus feats to make a mockery of the game if abused... for a martial-ish character.
Gestalt spellcasters can alter the Planes of existence and can summon sentient life ending apocalypse plagues... but I'm looking for a well-rounded 3/4 BAB archer that does Arcane blaster damage without being Arcane...
Trying to be as SAD on Wisdom as possible, without ridiculous cheese.
PS. Warpriest is an option, but the Orc HornBow makes it less appealing...
PoW Mystic is also an option. It is a Martial class, with an Asian aesthetic (which blends well with Monk), that adds elemental (fire, acid, cold, electricity) forces to their abilities. It is Wisdom-based, 3/4 BAB, and adds its own pool, called Animus. Its random maneuver mechanic does add complexity to the playing of the character, but also a limit on its abilities (as all readied maneuvers aren't available all at the start of combat)
You also have some out-of-combat utility, both from maneuvers and from Item Creation Feats to help the party out.
