I mean, for SSR servants, just the first copy + bond lvl 6 is enough to unlock Mana Loading. So for this servants, just a regular Kscope is enough to instant NP once Mana Loading is unlocked and maxed. Still a MLB Kaleido can be leveled to 100, which gives it more attack. But is still worthy the difference between lvl 80 and lvl 100, considering that the extra 20% NP bar is wasted? Or should be better to keep Kaleido at lvl 80 + extra copies? IE: MLB Kaleido + 1 Lvl 20 Kaleido vs Lvl80 Kaleido + Lvl40 Kaleido/2 lvl 20 Kaleidos.
Personally I dont feel like I need two 80% NP CEs, I have two kaleidos and I think that I never used both at the same time (Im considering just LB to lvl 40 one of them for this reason). So maybe I would still lvl Kaleido to 100 if I feel that more attack would be better than an extra 80% NP CE.
For SRs, in the other hand, is harder to unlock Mana Load since they get less coins than SSRs. But still, most of the farming SRs requires NP+ to be optimal, and an NP3 SR from Gen Pool also can unlock Mana Load at Bond 6.
There is also the issue with leveling Mana Load… it isnt cheap and in some cases requires materials from LBs that arent even released in NA yet. So for people that already has an MLB Kaleido, its going to still be usefull for a long time. In my case, with only two Kaleidos, I think that is probably that by the time that I get the 5th copy (if I ever get it), I would already have Mana Load ready in the servants that I want to be able to Instant NP.
So what do you think?
