Best female servant to look forward on 2019.

my personal favorite is maid/swimsuit baber alter rider. then tomoe then eresh.

I've only tested Abigail and I like her.
The animations are fun and her skills are odd. Her np gain is pretty low and her class also restricts her a bit. Another downside is her long cooldowns.
Her np is almost like a ST version of Amakusa and always handy.

I haven't got a proper jp team so my teams are kind of iffy so I can't use servants to their full potential but it is clear that her skills are meant as support.

I guess you could use her as main dps in an arts team since her attack is pretty high.

There's also the SE.RA.PH banners which have Meltlilith, Passionlip and Kiara.

Penth Musashi and Abigail

Servants to role for in terms of gameplay and waifuness :
Note: This is not a tierlist but Skadi is a must roll. Some 4 stars are even stronger than five stars thanks to support.
1. Skadi (obviously)
2. Katsushika Hokusai (The strongest foreigner and AOE arts servant in the game her skills and NP alone tell you why)
3. MHX Alter (Trash until Skadi gets release and when Skadi does oh boy does she do some big girl damage)
4. Brynhild (A meh servant before her buff. After buff she is a amazing semi-support which can turn anyone even berserkers into critting machines)
5. Caster Nero (Strong servant overall but her guts might make you force you into high IQ plays though)
6. Parvati (Skadi just turn her into Dark Sakura in HF route which fcks everything in her way)
7. Valkyrie (Just like Parvati but 3 in 1 and more consistent in NP spamming but Parvati does more dmg though in my testing)
8. Ereshkigal (I don't recommend rolling for her unless you like her as a waifu but her mats are unholy as hell oh right thats fitting as the goddess of the underworld)
9. Bradamante (Is situationally better than Eresh and has higher stats than her and works with Skadi but her NP spam consistency might pose a problem sometimes. She can debuff cleanse and give NP gain to others. She has guts paired with a strong def-up which means she's tankier than most servants couple that with her high HP. Her 1st skill makes it so she can deal as much dmg as buster cards with her arts and quick cards. Some people who waifu Eresh might think she's trash compared to Eresh and she has low attack. But... doesn't Eresh have lower attack than Bradamante? *thinking* Also her NP has a good chance of stunning all enemies)
10. Abigail (She wouldn't have made it in this list if she wasn't best-friends with Hokusai and a good daughter to the master and Penth and having a good NP and a decent first skill. Her problem is her berserker NP gain and HIGH COOLDOWNS because aside from her first skill her third and second skills aren't worth the effect and it's cooldown is just bad investment and return but she has the best ST Buster NP in the game though)
11. Qin Shi Huang (Neither a woman nor a man. But is the most busted Ruler to date along with Amakusa and Sherlock. You can waifu him/her since no gender. Easily one of the best servants in 2018 JP release to date along with Skadi, Hokusai and Valkyrie. His skills, NP and stats are just way to strong for a servant but so is Merlin with his skillset I guess)
12. Musashi (The meta in JP as of now is AOE quick and some ST quick servants can hold their own agaisnt breakbars. Buster is below quick as of now but they are neck in neck in the meta. But all that said Musashi is still decent and can hold her own but the state of the game does hurt her quite a bit in harder content still a good servant to pull for)
13. Okita (Though the meta is quick and she is a good servant. Her skills are outdated but that doesn't obsolete her. She just relies on her raw stats aka dmg, Np gain and star generating and her strat is NP Back to Back for the next couple of turns essetially taking out 3-4 breakbars without making the gimmick of harder fights take their toll on your servants gimmicks in JP suck balls. Okita, Musashi, Sigurd, Nero Bride and Prince of Lan Ling are the best sabers in the game as of now in JP imo. Though Sigurd's kit feels even more outdated than Okita's *Omegalul* but Sigurd can outdamage them both when critting just when critting)
