I was lucky enough to receive mitsuko and inari in the Atlantic summons.
my mitsuko is currently headed to the end of her second tier. using her in a team to test her out in raids and taking on teams up to 500 points above me I have not lost single match where an opponent has a blue attack hero.
the only thing I can say is that I don’t think people are understanding that her reflect means zero damage to anyone who is hit by blue and any aoe blue is dead in one shot. Thorne, Alasie, Richard, triton, isarnia, all useless if they survive they attack they have less than 100 hp everytime.
I have been fighting in platinum with around a regular 34 to 3500 team depending on opponent. with mitsuko leveled just to where she is currently I am now in diamond running a 3200 team
hope this information was helpful to anyone curious as to first impressions. good luck to all.
