Intro
Another rerun, but this time with a new roster of T-Dolls available, alongside farming routes!
Check below the drop for each map, as well as whether its T-Doll is worth farming or not, and how to farm it!
Note that all maps will unlock a farming route after being completed for the first time. The farming recommendations below will be considering said routes.

Map 1: M82

M82, not to be confused with the superior Inori (M82A1), is a middle of the road AR with the Charge Focus Skill, and that is about all there is to say about her. She doesn't provide any major advantage over any other AR, thanks to her burst nature. No current content favours bursty ARs which leaves M82 in the lurch of lacking a defined niche to really keep her around.
M82 does have one stealth value, that being she is semi-needed to complete one of the Griffon Side Stories. This does reward her with a Unity Skill with AK-Alfa, but this isn't very good or any major reason to use her, so this is a pure lore and story bonus and nothing else.
Farm if:
You are missing her for the index
You need her for the side story
You want collection gems
Skip if:
You have Enough ARs
You already have her for collection gems
1 AR + 0-1 HG, depending on equipment and fairies available. M4A1 not required.
Note that the map needs to be manually turn ended to complete the farm, because MICA reasons.
Map 2: OTs-14 "Groza"

Alas, Groza has fallen quite far from her heyday as the Night Queen, due to both shifts in the overall meta of Girls' Frontline and shifts in the types of content we are presented with. While she remains a powerful Night AR, a drip feed of buffs to her competition (AS Val Mod, 9A-91 with Chip Login SPEQ), along with fewer and fewer night missions, and no night rankings has left Groza out to dry. Not only has she lost her previous effectiveness in her niche, but her niche is simply no longer required in modern GFL.
Farm if:
You are missing her for the index
You need her for her gorgeous skins
You want collection gems
Skip if:
You have Enough ARs
You already have her for collection gems
You already levelled 9A-91 or modded AS VAL
1 AR + 0-1 HGs.
While they're weak enough to be finished by 1 AR, bringing an HG makes the farm safe from RNG if the Doggo echelon happens to spawn on the Helipad next to the Command Post.
As the enemies are not pre-spawned on the map, bringing 2 T-Dolls on Positions 4 and 7 guarantees they won't walk past you and cause the farm to fail. Alternatively, it makes farming this map more expensive, as you'll be ressuplying an HG as well.
RNGproof option
1 AR + 1HG, on Positions 4 and 7, in case Orthrus spawns right next to Command Post after starting the mission.
Cheaper option
1 AR, on Position 1, reset if Orthrus spawns right next to Command Post after starting the mission.
Map 3: HS2000

Of this group, HS2000 has by far the biggest upside. HP shields are as powerful a tool in the Commanders' hands now as they were when she first released in Isomer. While the windup time on HS2000's buff is longer than one might like the full team HP shield is still useful it's own right, and she remains a valuable pick for some rankings, as well as for generalized farming Echelons, allowing the DPS to stand and get shot without taking actual Damage, thus reducing repair needs and general player attentiveness considerably.
Farm if:
You are missing her for the index
You want collection gems
You want her for future cheap farms
Skip if:
You have enough P22s
You already have her for collection gems
M4 + 1 RF + 0-1 HGs
It's recommended that M4 is at least Mod II. For RFs, M14 is a safe pick.
Due to M4's low RoF during her Skill, as well as the RF's naturally low RoF, the HG should have RoF tiles (such as Stechkin, Welrod, HS2000, Five-Seven.
Position the T-Dolls on 1,4 and 7. If using only M4 and an RF Position them on 1 and 7.
Map 4: AUG Para

Having recently written the AK-74M analysis at the time of writing this, the word gimmick has started to lose all meaning, but there is some truth to attaching the label to AUG Para as well. The ability for her to convert her offensive stats into defensive ones, is less valuable than it sounds, as the ramp up time on her offensive mode is long, and cutting into her survival to boost her Damage output is not often a winning gamble in modern GFL. Her defensive boost is more worthwhile, with a shorter ramp up period, and more immediate returns on the stats gained.

While she is not going to break the meta open, AUG Para has her niche, and for those truly dedicated to the AR/SMG Echelon she will find her place there, after Commanders have already deployed the more traditional maintanks.
Farm if:
You think she's cute
You are actually that down bad for SMG Main Tanks
You are missing her for the index
You want collection gems
Skip if:
You already have her
You are Soulmuse and she's already stalked you across two servers and you want her to stop
You are Adam and treats her as your precious waifu's little sister
You're an AUGGERs through and through
M4 + 1 RF + 1 HGs
It's recommended that M4 is at least Mod II and have a #2 Processor chip equipped on her. For RFs, M14 is a safe pick.
Due to M4's low RoF during her Skill, as well as the RF's naturally low RoF, the HG should have RoF tiles (such as Stechkin, Welrod, HS2000, Five-Seven.
Position them on Position's 1, 4 and 7.
