That new 6* sounds like Kerria's perfect friend. And like a must have or every offenive teams of any types. But I will not try the gacha for the 6* anyway, due to my lasts results on the previous event hahaha.
Back to lower rarity girls, I'm a bit disappointed with Blood Iris after rarity growth. She has hard counter abilities and hard offensive abilities... It's just +60% ATK for herself and one ally + 30% for 3 other allies, up to +120 on boss fight for herself and one ally and +60% for 3 other allies. That's crazy. But... why a such good counter aside that? It's the total opposite of this. Well, her skill damaging 2 targets is not that good anyway.
I mean... the guts thing is not bad for a girl like that but the Counter as useful as Justicia's Counter. She can't really use it at full potential. Or if she does, she can't use her full offensive potential.
