Okay I'm not gonna bother discussing what happened in the VN, you raise some fair points but the situations in those don't really compare to a serious 1v1. All I wanna say is about that Archer scenario, she lost due to her cockiness(which you seemed to completely ignore in your reply), as she had a massive chance to kill Archer when he was weighed down by Atlas but instead chose to taunt him and get Caladbolg'd.

Back to the army point, she didn't use her Anti-Army spell on Archer, she was using single beams that he able to deflect and dodge, and some people actually speculate he was projecting a single petal of Rho Aias every time he deflected a beam because of how strong they're meant to be.

Even so, are you really saying that massive area of effect laser beams that scorch the earth couldn't hit the tightly packed soldiers of the Hetairoi? The lasers area of effect was so large she came close to hitting Kuzuki and Assassin. Or are you implying that in a packed army of thousands, they have enough agility and space to dodge EVERY single massive explosion from her lasers? I'm also going to bold this because you seem to ignore it, she doesn't even have to deal with the Army, she could just fly off, blocking those supposed homing arrows and spears with Argos, and wait for it to dissipate.

We don't even know the scope of her power, what if she can use Atlas on a massive area and immobilize a large portion of the army so they can't use their apparent A++ dodging skills? What if she has spells that are made to deal with massive amounts of enemies? She only uses 5 or 6 spells so it's hard to know.
