L5 crew upgrades?

[Red Wizard]

For the first time I'm torn on some of the crew upgrades, What are your thoughts on these: I'm playing on very hard if that matters.

Dietrich:
Conductivity: +1 Electro Core area of effect
Static: Electro Core casting cost reduces to 1 AP
(I've gone heavy on stunlock for my main character, so I'm leaning towards Conductivity)

Eiger
Sharpshooter: Upgrades Eiger's rifle to a Ranger Arms SM-3 (20 DMG, 6 round magazine, 2 armor piercing)
HuntressL Unlocks Wired Reflexes: +1 Movement, automatically dodges the first attack each round (1 AP, 3 turn duration, 4 turn cooldown)
(Thinking Sharpshooter because it's usually better to do more damage, but automatically dodging the first hit, plus healing the second makes her almost invulnerable, which seems super good)

Glory:
Enhanced Adrenals: Adrenal pump duration increased by 1 turn (5 turn cooldown)
Adrenal Injection: Glory's adrenal pump can be used to revive allies, shared cooldown (5 turn cooldown)
(Again, extra AP is nice, but in a game with limited revives, an unlimited skill is pretty powerful)

it's been a long time since I last ran this game but off the top of my head here are my thoughts.

AP is universally too valuable and larger area of effect comes with some issues especially if your player character gets in the thick as a melee or short ranged weapon. I think I tried conductivity once and ended up barely using the skill due to competing for AP.

For Eiger, I usually play her as long range and either run player character and/or glory for front. But if your player character is long range and avoid glory now and again and play eiger primarily through her shotgun at shorter range, then wired reflex can be good. But from a sniper position, she rarely takes damage so you often won't want to even spend the AP to trigger it over an extra snipe.

For Glory, I could see the adrenal injection in a blind playthrough with self-imposed no reloads. But if you know the run a bit, you tend to rely less on revives and again, AP is universally so valuable I never felt like it competed with enhanced adrenals.

Thanks. I went with Conductivity for Dietrich. He often times sits around and doesn't do much, and an extra +1 radius adds a lot of area. So far it's been useful.

Sharpshooter for Eiger. I play her close-mid range a lot, but she rarely takes hits already, and the damage on that gun is great.

I went with adrenals for Glory, but honestly I never bring her along unless it's forced. PC is a mage, but I still prefer the utility of having Dietrich along over her.

Dietrich: Static. Lower cost = extra action = more useful overall. Healing, totem, accuracy... whatnot. +1 area is quite situational.
Eiger: Sharpshooter = more dmg = more usefull overall than dodge cd (she's sniper anyway, so low risk of getting hit).
Glory: Enhanced adrenals. Anyone dies only if you mess up and even so by the endgame you're stocked on revival items. Better give Glory more action in long fights (which is hella case in endgame).
