The curse demerit on her are 1000 per 3 turn so its not quite that bad, unless it stacked when spammed then yeah it gonna be a bad time

I'm still not quite understand what's wrong with defense down tho, its not that bad tbh from my experience

It still useful against servants, because 5000 HP drain still big enough and the low cooldown on it mean you can ready with it, Who know when you use it against dying enemies and BAM, mission success

Still great on it, i mean its overtime damage for 5 turn so its still strong

Yes she kind of tricky but she still great tbh
