Okay so, I have a really big problem with these kind of OP servants, that being they're... way too OP.

So supposedly, Atsuko has 5 stargen 5% NP charge per turn. She also can buff an ally's Quick performance, crit damage and star absorption with her 1st skill. She also can remove an ally's debuff, charge their NP gauge per turn, and increase their NP damage with her 2nd skill. And she also can Increase party's attack, female allies' defense, and AoE charm male enemies with her 3rd skill. And PLUS, She also can grants party Invincibility, heal them, generate crit stars, and charge their NP gauge with her NP.

This is like, legit powercreeping to it's finest, She's not only a jack-of-all-trades support, but master of all (yeah she can't debuff but let's ignore that for a minute). She's legit a fusion between Waver, Tamamo, Skadi, and Merlin, and those support I listed has some kind of flaw to compensate for their OP-ness.

Waver can charge allies NP, increase their crit damage, attack, and defense, plus he can stun enemies and decrease their defense and NP gauge. But Waver can't grant party heals or invincibility of some sort, he can only prevent/cut the damage but he can't fix it, plus the stun on his NP is quite unreliable.

Tamamo can decrease an enemy NP gauge, increase allies NP damage, buff her own defense, heals and increase an ally's Arts performance, reduces party's skill cooldown, heals party, and charges party's NP gauge. But Tamamo can't cut the damage like Waver does, she can only fix it.

Skadi can increase an ally's Quick performance and Quick crit damage, AoE debuff enemies' defense and crit attack chance, charge one ally's NP, increase party's crit damage, gives them evasion and instant death immunity, and cuts their damage. But Skadi can't heal, her crit damage buff from her NP only lasts for 3 attacks 5 turns, her evade only lasts for 1 attack 3 turns, and her instant death immunity is really niche.

Merlin has 5% NP per turn passive, can increase party's attack and charge their NP gauge, grants party invincibility, increase an ally's buster performance, crit damage, and max health. And with his NP, heals and charge party's NP gauge per turn, and gains crit stars per turn. But Merlin can't provide defense outside of his invincibility meaning if the enemy can do high damage for more than one turn, all Merlin can do is to just heal them per turn and hope that a wild-really-high-crit doesn't appear.

Those flaws may be quite minor, but they do exist. This is not the case with Atsuko at all, not only her buffs gives really high numbers (or have a really high chance of triggering) especially with her 2nd skill that's also targetable, all her flaw is that she can't really do damage but that's not what supports are for. And no, her defense buff being only female servants exclusive isn't that big of a flaw, her other buffs overshadows that by a mile away.
