FYI, Stheno's effective base attack is 8086.5, which is only 94.5 lower than Siegfried. And taking the damage formula into account, that isn't really much of a difference at all. Further, her stargen is better than Siegfried's. And despite having an NP drain and male charm as her other two skills, that's still better than a heal and minor NP gain boost. She also has a 50% magic resistance, which while niche, is better than Sumanai's 0% (wow, he doesn't even have the Saber Class base Magic Resistance skill).
