Thanks Wutan and all for your input. And yeah, it's REALLY tempting to stack all them "4.3x to 1 enemy / absorb HP" all in one team O_O

What one team was Kerria debuff, and one team is (for example) Rainbow Rose featured critical? Would you say separating the girls like this would be more effective than shoving them all in one team?

And what about healing girls in these teams, whether be E. Cactus, Adenium, etc., would it be worth it to switch one slot for one of these girls?
