Why would Valerie not have outflank? You're not making sense in that particular case. It's something you probably take on any front liner anyway. Teamwork feats aren't an exclusive feature of the Inquisitor class, only "solo tactics" is but with good feats like outflank which you end taking on anyone it doesn't matter. And if anyone stands near her on the front he/she might get targeted as well so you might give him/her shield wall which means Valerie can use it too. Also does Jaethal start with heavy armor proficiency? Inquisitors don't have it by default, and you calculated the AC assuming a heavy armor. And that costs another feat which an inquisitor doesn't have that many or a dip into fighter class. And also Valerie has more HP which also sometimes comes in play when tanking.In a game where spells rule endgame, tankyness is not only AC. I will take my Undead tank with many tools for many situations over a few more AC, thank you very much. She has Shield Wall and Outflank. Harrim gives her +2 ac just by standing near, Nok Nok always flanks with her and gives her +2 more attack. This is another thing Val does not have.You can always use agile weapon, you know?Ok, yes you can make her small and raise her Dex on level up instead of Strength. Then she will hit even less stuff and enemy AI will decide to attack others...You can easily get +7 dex bonus on Valerie without items even if you take +2 STR from her quest instead of +2 DEX.
But this conversation is pointless. You don't use full kit potential to increase tankiness but then complain that character is not tanky.
She also has Back to Back and anyone flanking her does not get the +2 bonus to hit her. For Val you would need to take Back to back with multiple characters.
EDIT: OK in this game lvl 13 tower shield specialist gets immunity to flank. But with multi to Vivi and possibly Stalwart Defender, does anyone get her to lvl 13 by lvl 16/17?
There certainly is a good point to be made about Jaethal immunities being more useful than AC, especially as the game progresses, but the one about teamwork feats really doesn't hold much value. Also Jaethal has her special healing "needs". Which might not be a big issue if you keep her an Inquisitor but still limits her a bit and so the undead status is not pure gain as you make it out to be.
