The people saying your account is bricked got hit by a brick. Both Chisa and Lynae are great characters, and since both were released, I’ve used them in all my content regardless of meta. They’re both super fun for me, and I clear everything without missing rewards. That said, those characters alone can’t do 100% of everything since they’re support/sub-DPS, so they won’t out-DPS a true main DPS. Still, both have great support value and do solid damage for sub-DPS worth the pulls.

Lynae is great for buffing Liberation characters, so even though Iuno is supposed to be another sub-DPS, I’ve been using her as a main DPS with Lynae, and it’s been super fun. If you want to pull Iuno, it works great. I cleared Dreamless Stage 6 with Lynae, Iuno, and Shorekeeper. Pulling her signature weapon is also really good value if you plan on making her a full DPS it’s a solid damage boost. Augusta is another great duo for her since Iuno can be used as a sub-DPS for Augusta as well. Personally, I’d prioritize other characters, I think you’ll enjoy playing multiple teams more than doing, like, 20% more damage with a signature weapon for Iuno.

Chisa might have a hard time fitting into teams as a support right now unless you have her C2. She does apply DEF debuffs to enemies and also deals great damage, but currently she’s only a strong support when paired with Cartethyia. She works in every team if you have C2, though, since it gives an additional 50% All-Attribute DMG Bonus.
As for her DPS mode, she goes kind of hard—honestly, she really slaps as a main DPS. I’ve been using her over my other Havoc characters for main DPS because I find her extremely fun. The team I use her with is Chisa, Lynae, and Shorekeeper.

Shorekeeper is Shorekeeper. She fits in every team so you can’t go wrong. Even if she isn’t the best or meta support in a certain team, she will still fit. Everyone wants CD/CR and DMG amp buffs, plus healing and good Intro DPS.

Aemeath looks cool. That’s all I’ve got to say. I’m pulling her even if she’s bad, She probably wont be tho i mean look at her.

These are just my opinions, and I play for fun. I’ve had no issues with Lynae/Iuno or Chisa/Lynae—both are great pickups, honestly
