This time they’re all on the same banner, which is actually a good thing in this case as they always keep the same base focus rate regardless of how many focuses they share.
If you want an up to date TLDR on who to go for, Tiki, Peony, and Marth have managed to stay relevant in the current meta for their own reasons. Fjorm and Veronica are niche, but have seen some usage here or there (I say as my Fjorm lead is auto battling Agito Twins on expert). Chrom is weeping in the corner after god smacked the Awakening out of him with a book. Alfonse and Sharena are decent and are available permanently from now on.
