Yes

Everyone is worth it

Yeah

A lot of the low rarity servants are really good so i’ll recommend some to level first

Saber: Julius Caesar, Bedivere (story locked)

Archer: Robin Hood, Euryale, Paris, Arash

Lancer: Cu, Proto Cu, Gareth

Rider: Ushiwakamaru, Georgios (bond CE especially)

Assassin: Cursed Arm Hassan, Hundred Personas, Fuuma Kotarou

Caster: Hans, Asclepius (story locked)

Berserker: Lu Bu, Spartacus

Definitely level your yang and ibaraki because they’re both really good as well

And don’t forget to level your kouhai mashu

Like Nano said everyone is worth it. As even a 2* or 3* can be just as good as a 5* ;)

Especially anyone not named Angra lol

Also there is a amount of points u can use on team and u cant fill it up with a full 5☆ team and 5☆ ce's

Hello! First of all, congrats for getting Yang! Secondly, yep, if you can, upgrade all servants that you have.

1st level up Mash.. shes nice and important...

2nd level up thes ones u can in terms of mats(items u have so u can futher level them up)

3rd level the ones u need to make a good comp for starters(ex. Arash, Hans)

Agree with what everyone already said, and I’d like to add: if you’re struggling between who to use materials on, just go for the character you like/enjoy using more first. I find it to be more fun to use my favorites :)
