Well, after some time in "log in + clear event in the last week" mode I got my interest to the game back... and started checking what servants do I have from those whom I didn't raised yet, and noticed this list:
Arthur (Prototype).
Ozzy.
Scheherazade
Xuanzang Sanzang
And I kinda would like to ask is there any sense in raising them given that I have a lack of QP and Lores, plus, probably have someone to fill their role?
For sabers I have: Siegfried, OG Altria, Mushashi, Charlie.
For riders, well here my choice is quite poorer: Constantine (well, even given that he is support buster crits under Merlin still works to kills almost any boss), Mandricardo, Ushi.
For aoe casters I have: Anastasia (even given that Scheherazade is slightly better Anastasia is already maxed out) and Aesc.
For st casrers I have: Sheba and Circe.
So the point\question is at whom from those should I take a closer look?
