you didn't have a single encounter that stressed it for even half its capacity, neither did you exhaust the knife - if you make any use of stealth, it's probable you never lost more than 20% of shield juice, so why insist on a perk to have an extra 35% you're not missing
It still works in some areas. Such as lots of incoming frag grenades, DC mushroom forest, locusts, spitting serpents and so on. It also helps with the SMG build when enemies attack from a distance, have high evasion and are spaced far between.
Also, fully speced out versatility? Is that really a thing?
It's a real bitch to play like that. The build only started working on level 15. That's why I used Classic to begin with. I've had to stealth through Depot A and rush Chemistry for Mk3/4 grenades ASAP. But then the 9-round 8.6mm bursts got so powerful that I almost never got to use W3C ammo. Only enemies like industrial robots took more than 1-2 bursts to the face.
Styg should increase Tchort's HP to something like 20k. And add energy shield durability.
