MND Patchy:I hear people actually use this. She'd probably take 0 damage from almost any magic, although physicals still wipe her and her damage would go down a bit. And her damage isn't really exciting later in the game in the first place... :\
DEF Remilia:Tried it; her survivability really doesn't go up all that much, and her offensive power takes a huge hit. I'd recommend ATK Remi over this.
ATK Meiling:Ha ha, old chap! Well, Healer would be a better heal... it's not the worst idea to use, I guess.
ATK Komachi:A good idea. Her HP takes a huge hit from this, trust me, but she'll do great damage.
DEF Wriggle:She doesn't really need her ATK anyway, mostly just makes her a useful person for randoms.
DEF Yuugi:She'll still get wiped by magic anyway, so

SPD Chen:olololol. IMO you'd be better off doing SPD Aya since her ATK isn't as exciting and she can SPD buff. SPD Aya would be an interesting thing to try, actually.
