Should i spend them all right now on the FP gacha or just ignore them until later? I already got the 3 stars i want (Hans, Cursed Arm, Cu, and Euryale), but getting them to NP5 would certainly be awesome. The problem is i don't know if they will add another great 3 star servants to the FP gacha in the future.
I'd suggest spending them on the gacha already as if you get craft essences you can make bombs during the super and great success rate up otherwise you have fous, mana prisms and a bunch of NP5 budget servants for when you need to use too many high cost CEs in events, saving is only really something to do when you've got everyone to a decent NP level and there's no rate-ups on CE enhancing
Based on your servants, I'll assume you're a new player. In my opinion, save those points for events, so you can roll on 3 star event CEs which could help you minimize farming especially if don't roll on that banner. Just use the free daily summon and eventually you'll get them at NP5.
Just rol the 10X Daily Free Summon of FP and keep the points. You will eventually NP5 them, I play this game since 2 months ago (everyday, and everyday I roll the free FP facha), and right now this gave me NP 5 Kojirou, Arah, CA Hassan, Mata-Hari NP 4 Jenkyll (1 of them is the free one you get from London chapter...), NP3 Kiyo (same, from Orleans), NP4 Blackbeard, NP2 Hektor and a third Euryale (first two came in different quarts gachas).
Also, I MLB Azoth Blade, Sorcery Ore, and I am on the third LB Moon Cell Automation and second LB Dragon Meridian.
Keep those many point just for the events, the 3* CEs of the Events, who are very important for farming their most common currency, can be get from there as well (not to mention, they are limited time CEs that you can only get during the events, and MLB them makes the stressing grind incedibly softer).
The next event (summer) is VERY grindy, with many different currencies to farm, and farming needed to unlock the main plot, and will be hard to farm specially if you want to spent on some of those rare mats of the shop as well (For example, I gave up on NP3 my Kintoki Rider for some mats who simply wont drop ever, and I will likely do it again for the damn Seeds of Yggdrasil- need extra 25 of them for the 3 Cus+Robin- and 4 Dragon Reverse Scales for Euryale and Ko-Gil).
And since nobody will (or even should...) do many extra multiple multi-rolls just to get a 3rd or 4th 3* CE, no matter how useful it is...
Save them for the summer event so you can get the event 3* CE's without needing to spend quartz on the gacha. There will be 3 stars added in the future but that's A LONG way out. Next year at the earliest, with one of them limited. Roll the daily free 10x FP summon and you'll NP5 them in no time, to the point you'll be getting dupes.
