1. Erza vs Kagura vs Minerva

2. Magic Games arc was by far the best arc of the show and in my opinion, if you compare arcs, easy one of the best 20 arcs ever made in an anime. Surpassed by Espada Arc from Bleach and such, only by the best of the best arcs in the best of anime. I was thrilled watching it. Another example is that some say Death Note, Overlord, Vinland Saga, Trigun, Fate Stay Night, My Hero Academia, etc. are 10/10 anime. Might be but they don't have an arc of that quality, not even close. Top 20 anime arcs ever, easy.
3. Fan service completely satisfied: on women, damage is cumulated in degree of cloth thorn, and things shown.
(as one can easily see in the video/amv above)
LE: Erza is invincible as she can literally change her clothes in a blink of an eye!
