Mama's dream team?
Well, i allready started to invest in Mama (grailed to 96, aim to 100) and now thinking about her teammates. Obvious, crit generator and support. With support i have 0 problems, Waver for the win. But star maker is troublesome. Right now i have Kiritsugu (grailed to 90 for "fan" reasons), he have a good synergy with Mama cuz of combo with Mama's evade and his target taunt. He even can take a role of crit dd if Mama goes down (passive and skill to up his crit dmg). So a question is - if Kiritsugu gonna be still good in future or better to aim for Jack as stars maker in anniversary banners? I aim for Jeanne as well for my Vlad/Jeanne/Tamamo team, so i need to decide on one of them. And pls, dont answer like "whatever, pick support", cuz i prefer to use only servants i have for gameplay/fun reasons. Supports is placed last in all my teams...
If that's the case I don't think it's worth specifically rolling for Jack. In terms of which anniversary banner, just roll whichever has more servants you want/need. Since you also need tamamo, I would roll the 4 horsemen, since with Jack and tamamo you have a 1/5 chance of getting something you want, but that's only if those (and jeanne) are the only ones in both banners that you want. I don't know how you feel about all the other servants so that's all I can say.
BTW, just gonna add that you don't necessarily need jeanne for vlad. Unless there's some other reason you want to specifically use jeanne+vlad+tamamo for a team, you can sub jeanne out for any other arts servant and the team would still work almost as well, and waver is imo currently a better fit for that particular team, at least until Jeanne's strengthening quest which isn't going to be for a while.
I allready have Vlad and Tamamo, right now i use Deon with them, want to swap him with Jeanne. Deon's NP is kinda sucks, but skillset is amazing. But with Deon there is no escape from aoe NP. Actually i always wanted Jeanne for waifu reasons, but while beating the hell out of Gozen on 3BP i fell in love not only for Jeanne legs, but for her NP as well.
You can never go wrong with Jack : nice stats, one of the best Boss Killer in the game, one of the best star generator, a great NP Gain, she has an Evade Skill, a remove buff, a healing with a very low cooldown...
I hate Loli character but Jack is the exception for me.
Even if you have Shuten and Kiritusgu, having Jack is a big plus.
