From a very young age, Elsa lost her father.
She didn't have many memories of the man except when he was teaching her combat techniques, and reading books of war strategies to her.
Growing up, Elsa digested these few experiences she had with her father, greedily soaking them in like a sponge.
Number 1, it was the reason for her unnatural grasp over combat.

Number 2, it was the reason for Elsa's unreal tactical mind and sense.
No matter how unusual and powerful they were as apprentice rank awakened warriors, there was no way that they stood a chance against an Advanced rank awakened, not to talk of a Heimdall who was that powerful.
