Sigrun's skillset alone shows how utterly unplanned anything is in this game anymore.
But yeah, we just need Bridal Alts for Klein and Clarine now to fully complete the Reglay set.
In regards to sets, we'd also need Bridal Alts for Chrom, Florina, Robin, Eliwood and the Summoner (Charlotte is open for business, while Sanaki pairing with anybody won't be not creepy).
So something that's rather unfortunate about all of this is that of the now 13 (Charlotte, Inigo, Shigure, Noire, Veronica, Mikoto, Greil, Bruno, Mareeta, Sigrun, Tanith, Pent and Louise) characters who made it into FEH Alt first, only 1 of them has gotten their base version added afterwards. This wasn't such a big problem when you're talking either kids with alternate versions already (paging Laslow), OCs who's plot isn't done yet (the Embla siblings), or are characters that were hard pressed to get in normally (Greil and Mikoto); but characters who ranked very high on the CYL (Louise made it to rank 23 in CYL3 and still had a commanding rank 74 performance in CYL2) or was the heavyweight of their game (Mareeta is perpetually within 776's top 5) getting stuck in the Altception is pretty dire.
And just to rub salt in the wound, November's Adrift banner was nothing but Alts (even Mikoto isn't her base game Queen of Hoshido self but the Young Azura's dreamified self), and yet was still treated as the main banner for the month (either that or the OC pair of Ylgr and Surtr which is its own joke), especially since December didn't even get one, and January lost one from last year to a brand new round of Seasonal (because there weren't enough Camillas in the game yet). Last Fall was incredibly dire and this one will somehow be even worse. Mark my words.
At least I'm not the only one who's not happy with the way FEH's been handled.
