Should I choose her as my Healer ?
She's a subpar healer (compare to other 5* healers, or even some 4* supports who can heal). Her main role is actually dps booster through her Frenzy buff. However, the upcoming new child Wodan should replace her for that role as she also grants Frenzy to a child with highest ATK, making her much more easier to use than Metis.
Her slide and drive are good for wasting the enemies fever time in pvp, but you pretty much have to play manually to if you want to use her effectively.
There are better healers out there, Maat and the newly released Pomona being two choices. Maat is the go-to as she fits in PvE and WB. Pomona fits nicely into WB, Rebirth and PvE due to her debuff cleanse, even if her healing isn't as spread out as Maat's. Neptune is a supporter but is the preeminent healer in ragna and PvP as she boost speed and gives atk buffs along with her healing.Metis is interesting due to her slide and drive. Immortality is nice but too situational for me. I'd rather smack things with crit boosted Red Bathory fast over trying to outlast an opposing fever and returning fire. Berserk is also interesting but again too situational for me. I'm also not a fan of the auto stun post berserk. If you're starting out and this is your first 5 star healer, she will more than suffice. She'll last you long enough to get other options on your squad.
I got her at +5 and I use her sometimes
the bad things about her is not only she is a bad healerand also her art styleher head is kind detach from her bodyso no reason to keep her
Suggestion, pick natural *5 for the best result
I recorded a few matches for you using Metis a while ago (waited for quality to improve but YT processing is weird)https://www.youtube.com/watch?v=rUCZrQ-hnDsYou can skip to 5:20 for a summary on what Metis can do and you can decide for yourself if she's worth investing on.
Metis is Trash.
never used her but she's decent overall
Not a great pick. Simply because there are better supporters and healers out there. Especially when equipped with proper gear and Soul Carta. Not too trash to be expended either.
