Sorry for the long delay on this answer Anno. Personally, I don't much like the idea of divine spirit components becoming summonable servants, mostly because it defeats the purpose of them being components. Like, for example with Lip, what exactly can she do that Bryn, Parvati, and Durga can't? Trash and Crush? That's just something Lip has by default thanks to BB. And Breast Valley nothing put in can get out, save for her master but that's a FGO thing. The idea of High Servats being compose of several divine spirits was always that we wouldn't get all of them as summonable servants but now that we have, at least in Lip's case, there isn't really a reason for Lip to exist outside of being a character and even then she doesn't get much screen time when compared to BB and Melt. In short, Durga becoming her own servant was something I did not like, especially more so when they just made her and Kali Sakura faces. Yes it makes sense given Parvati was a Sakura face but that just highlights the silliness of making the two separate summonable servants. You already had Lip why go and make them both Sakura faces when you already had psude-servant parvati and durga as sakura faces with Lip?
