After this legendary banner and unless the following legendary banners impress me, I plan to save until either December or January, for Marth, more Hector, and probably Tiki (they're arguably the best legendaries now). Probably that should give me about 1k orbs. Although this will have me delay my Soleil merges for awhile, unless I get copies on free summons (+6 now).
And while also doing that, I intend to invest on the Askr trio (already did Sharena, thinking of Alfonse and Anna).
I'm considering saving too, but I'm not sure if it's worth it. But I have a long time to save to +10 Alm because it'll probably be until 2022 until they run him again color sharing with Raigh, Sophia, and Wrys dancer alt. I'd also have to spend whenever Alm or Roy finally gets their legendary versions.
