Like... let's see, with *s for limited/special that wouldn't be in the ticket anyway...
Naveed - Really have no use for. I could see it if there was any indication we'd get longer fights as I know his buffs lean towards that.
Mikoto - Obviously, very strong. Potential HMS alt without eldwater cost of Vanessa and no tablet farming, though I'm not itching to make an alt especially as I still only have 1 UB Cerb (really 2 copies 0UB, but) or Pele.
Ezelith - Have her; she's fine.
*Gala Sarisse - Seems strong/weird, and I like ranged. Would have been interesting as an HMS alt (same dragon issue applies) and would probably use over Ezelith in other vs wind content when not being Verica.
Xander - Have him from last free 5* ticket, have not used him much but obviously like his striker buff.
Xainfried - Previously basically 0 interest; now I do have interest for High Brun. But I also am very likely to skip High Brun and do the next high dragon instead.
Lily - Have her, she's great.
*D. Cleo - Like 0 interest as she seems neat, but I have Orsem (and now Luther) and I couldn't care about using her when I have Lily+Xander already.
Louise - I have Eleonora, so unless Eleonora totally can't do High Mercury... And even then I'd probably rather go Lowen?
Hawk - lol, also see above
Maribelle - More interest in wands than bows, seems very powerful, would gladly have her.
Julietta - Seems good for IO, and maybe for future content? Would be cool to have.
Annelie - Seems... neat? But I don't love the clown look in-game and my third light lance to cycle through isn't super appealing, even if she'd help with IO.
Lucretia - I have Amane and have like 0 interest in making her redundant, so this is another "only if the 4* can't do the eventual high dragon". ...I also think her art is bad.
Hildegard - please bless me to make all IOs easier to auto
*H. Elly - I used her friend skill so much during Halloween that it made me want her. Would have been an excellent foundation for my light team, which remains shaky even now.
Nefaria - Have her from paid 5* ticket. Good enough, better than expected. Could use her or Orion for inevitable high dragon, probably her with Nidhogg if MUB Juggernaut (which I'm an unbind away from) isn't enough for Orion.
*Ieyasu - Obviously strong, and I definitely liked his character the most of the 5* characters in event stories. So would have gladly welcomed him.
so like... I need actually gameplay reasons to want these characters and currently that doesn't exist for a lot of them? I think I'd mostly want a melee wind (so the upcoming axe is kinda appealing?), a non-lance melee light, or a blindness res melee dark, but a 4* or two of the last would already be more than fine...
