Every character in PF is a gimmick.
Only chapter 1 in P:K has:
1. Jaethal, good stats for almost any class, undead immunities, immortal (!)
2. Regongar, 19 STR, one of the strongest melee classes in the game and easier-to-use version of it
3. Octavia, optimized for strongest DD-caster build in the game, 19 int
Chapter 2
1. Jubilost, strong class, 95% optimal build
2. Ekun, optimized simple Archer build with trip-on-bite pet, 30+ point buy
Chapter 3
Nok-Nok, optimized knife-master with 23 DEX, no comments
But yes, Valerie has 14 STR and Amiri's sword sucks. I'll give you that.
-Jaethal is "neither fish nor fowl." Inquisitor is an oddball class that doesn't fit a clear role. The PF party is hurting for good healers early on and she doesn't help matters being undead.
-Regongar is fine but slow grower. Magus requires intense micro to reach full effectiveness and burns out of points quickly. Not ideal for a support character in a RTwP game with hordes of enemies. Tell me most people wouldn't be better off with just a straight fighter or sorcerer. He's also
chaotic evil , and you can't get rid of him, unlike BG companions who are all 100% optional.
-Octavia is good but multiclass hurts caster progression by delaying spell slots. No straight mages available in PF. Sure she's great at level 20 but you need to play her from levels 1-19 too. But she is one of the better ones. Although she has all that point buy and still dumped CON? r u srs? Transmutation is one of the weaker specialists too.
-Harrim is a lowish Wis cleric. wat? You have one job.
-Tristian is okay as a healbot (he was bugged at launch) but oh wait, he's gone now because story. Fuck you. Hope your party comp didn't depend on your healer or anything.
-Linzi is good but her Cha should be higher. 3E/PF casters are all about the casting stat. She's still never be as good as a full sorc/wizard.
-Jubilost is another odd class that requires micro and burns out of powers. He's great in the right group but again how much more effective is he than a straight archer or full mage? Given the rate of encounters he blows through his bombs in a couple fights.
-Ekun is so good I wonder if he was put into the game by mistake. Like an intern made a really effective character and the devs didn't notice until it was too late to change it.
-Nok nok is another evil character you can't ditch, a glass cannon who gets insta-gibbed by all the bruiser PF enemies.
This is the whole roster. If you don't like these character you better have the foresight to hire mercs at level 1 before the cost becomes unaffordable. Niche builds would make more sense in a game with a larger cast. Since you have to build a party from these options they should have been A. more broadly specced to fit into general archetypes and B. Not been a bunch of backstabbing a-holes who fuck things up constantly in unavoidable ways.
