My account is only days old and I manage to reach around level 60 above. I'm still around at America Singularity. I am wondering which servants should I enhance since Camelot, Babylonia and Solomon Singularities are near for me.
My servants are:
Mash: Level 45
Quetzalcoatl: Level 57
Lancelot: Level 46
For camelot you should rush euryale if you have one and lancelot(saber),level them to max asap,in camelot there are a lot of sabers and some lancers. In babylon max lancelot and kiritsugu and ofc mash. For solomon max Quetzacoatl. However. unless you want to rush the story i suggest you to max level Quet first and mash after. Quet is one of the best riders in the game and will help you a lot. Try farm some embers from chaldea gate.
For camelot, maybe Eurayle since there's a lot of sabers there and the final boss is a lancer.
For babylonia, there's a lot of lancers and mixed classes. This singularity is a lot easier than the hell that was camelot, imo you'll probably get by. If in doubt just add Mash in your team. Post camelot Mash carries every f2p comp.
For solomon, just make sure you're funneling bond points to your dps servants, preferably servants with single target NPs.
You seem to have a good pool of SRs so you probably won't have that hard of time. In desperate times, just rely on support and command seals (never quartz!!!) I don't have Elena but I hear she's a great support so enhancing her is also a good investment.
I'm gonna jump on the Euryale bandwagon for Camelot, her archer class coupled with extra damage against males, the ability to charm males, and her NP self-charge/drain are too good to pass up for certain battles in that particular chapter.
For Camelot, lots of male Saber bosses, raise Euryale, but David 2nd skill is a lso a lifesaver, level that as well, to at least 6, to reduce cooldown. There's one archer who is weak to sabers (Tristan), ans the final boss is Lancer, so, raise Saberlot the maximun you can (he needs the freaking medals for 3rd ascension...), as his crits are really good...Hans is his right arm.
Post Camelot Mash 1rst skill becomes really good, you will like to max that to 10 as soon as possible.
Babylon has lots of Lancer and Rider mobs, so AOE Saber and AOE Assassins are a must...you can use AOE berserkers as a risky option.
Again, IF you are not rushing massively the plot, level Quets first than all this, and then Helena, an excelent support, just with obscene cooldowns.
Of the lower star servants, Georgios, CA Hassan, Asterios, Hans, Shakespeare and Mozart are very good to invest.
