It is problematic because it occupies the B-slot, which blocks two important competitors and potentially a third:
1. Null follow-up, which is not a problem for Eir because she has something just as good if not better on her weapon
2. Windsweep, which is still an issue for Eir
3. Guard, which can in some cases stand in for NFU.
(4. Special spiral, which is possibly the best way to pull off the miracle gimmick, but this gimmick doesn't work against bold fighter or brave weapons anyways)
Here's the thing. Sorcery blade is not going to be common (maybe on the frontliner of an AR defense setup? But it's a hard skill to use in general), so mainly it's dragon breaths that are the issue. So you need good res and problematic def for mythic boost to make sense. (If you have good def AND res like Kliff just use guard and tank the QR double.) So let's say your name is Kaze and you go for mythic boost. Against any non-dragon DC+QR tank you're totally screwed. If you go for windsweep instead of mythic boost, you can sweep anything besides dragons that hit your def, and you have your res to cover against mages, whereas if you use mythic boost, you're in huge, often fatal trouble against a lot of non-dragon DCs.
I don't see Eir being good fodder.
This skill is only to tank dragons by mages and daggers with high res and poor defense, nothing at all!
Also, you can build close counter to tank dragons now with it. Not a problem, they are at meta, different by year ago. But also Eir s weapon is unique to block doubles when you atk a vegeful fighter dragon or Quick ripost dragon.
Hint:
you doest suffer damage if you put fury during enemy's phase. A good call to tank a bit more with better offense and spd.
Windsweep limits your attacks to one, and this B slot doesn't. It also lets you facetank Veronica without taking any damage at all. This is like the AR skill personified. So like if I'm facing some scrub Nowi with Kaze and I have Iceberg. I hit her, she counters my RES, and then it applies on the next turn. If I used windsweep not only do I attack once but I also die because shes hitting my Def twice. Watersweep you hit once too but you live. No one is dying though. It will be a problem against armors but I dont consider this a chipping skill.
Archers dont really run it because of firesweep bow. Daggers run it to chip and debuff. I think this skill is to combat dragons and tank healers which is a nice effect for arena. But windsweep cant work on dragons it only applies on physical opponents. Watersweep does dragons and mages.
If you want to tank Veronica without taking damage I think the better strategy is to have 50 res, which is gaining popularity in the mage-heavy (especially cavalry mage) AR meta, or using TA+raven which the cheater can't do a thing about. The 6 HP heal can even be counterproductive because it might disable your brazen (unless you use fury + brazen atk/res, which is by no means absurd with mythic boost).
Now, in what situation can you afford to hit refined-breath Nowi like that twice? Certainly not while four or five of her teammates are sitting around waiting to have you for lunch. By the time you get to a situation where you can afford to two-round her like that I think you have other options for dealing with her which don't involve such expensive fodder.
But you don't consider this a chip/debuff skill so you probably see its value differently from me. If I'm not trying to blast through them I want to make sure I don't get one-rounded, so I don't quite see where this skill fits in
Kaze, Deirdre and Julia using close counter could use it to take in both dragons and staff units better.
Kaze doesn't need the B skill for quick riptose or guard and D&J can oneshot dragons with it without needing to only use it on the player phase.
Julius also might like it, but he'll need a qr seal.
You think the Naga blooded can just go for vantage maybe?
CC Kaze is an interesting idea. Give him cloud maiougi too, because otherwise he might not hit hard enough to get through their high defenses. But for that matter why not just use desperation and double through them?
Well, the idea is not just the anti-adaptive damage, but also the anti-wrathful and the healing.
This skill could allow units to bait out Veronica on AR. Even with a dancer backing her up. Since Veronica often blasts enemies after getting that spectrum 8 boost.
Getting rid of wrathful and healing some chip might help with the safety.
The other thing is that dragons are often not alone.
With this skill you can safely set a unit in the range of multiple dragons, so no need to pick em off one by one. And Deirdre &Julia won't have to worry about a sudden one shot from a red dragon. Given their super poor def.
Anti-wrathful: TA+raven seems more effective to me, especially because Veronica's debuff means a lot of units will only be able to hit back once so you want to let her charge up your glimmer and stick it to her.
Healing: seems to be the most compelling aspect of the skill so far
And what I meant about Julia and Deirdre was CC + vantage. If there's someone there to hit her def that's not a dragon, aren't they screwed, mythic boost or not?
Well, maybe but it then you need to use a character with that restrictive set. Instead of one who can do something else.
The healing seems nice for high def/res units. Given that they often take small bits of damage. It can help them surive waves of chips.
That is a flaw in the idea, yes.
Overall I see this skill as a nice collection of skills that would have been too weak on their own.
The best way to make use out of it is to find a way to use multiple effects.
Not just anti adaptive, anti staff or chip healing.
