Stealth as a mechanic in a game like Darktide does not mesh well with the current rhythm of the game and the 2 classes that have it would be better off if those paths were reworked.
Veteran stealth is lackluster as a class ability and has some utility but it functions more as a support choice that has a better option in VOC that affects the team
Zealot has their stealth in a better spot for active gameplay purposes with its gimmick of being able to nuke bosses but outside of it does not contribute much in the gameplay
I believe that Zealots stealth pathway SHOULD be reworked back into the cut content for it being a blessing ability kind of a mix between Markus Kruber Grail knight and Warrior Priest where it can be chosen to buff allies or yourself and nodes that can give a flat CDR for applying it to allies/yourself and a further node that makes it able to target PINGED targets to deal single target nuking damage but with no CDR since it does not target allies or yourself and it should one shot elites/specials but it will not one shot bosses, but still nuke their health or apply massive permanent debuffs
For Veteran his should have been a “Weapons Specialist” ability where he can whip out heavier wargear to suit the battle and the nodes would reflect what wargear/amplify what they are bringing so at base it would be either a Heavy Stubber/Hellgun and then either a Grenade Launcher or Melta so that they can balance around the ability rather than a ranged weapon, the cooldown on it would be I’d say equivalent to Point Blank Barrage as its one of the longest cooldowns in the game currently and it should only regenerate cooldown once its been either used or swapped off and if you swap off it early it regains a portion of the unused ammo/ability charge maybe around 50% of remaining charge with a node that can change that to 80%
I just think stealth in this game is a lazy mechanic that doesn’t feel good in the moment to moment gameplay and contributes minimally to the game and your team as a whole compared to other options.
