Why is Minfilia so darn hot?

[dinnertime]

I really can't tolerate people who dislike a character because they believe they are of no use for them, it sounds so selfish. Does it really matter that she could fight or not? She's not really someone who's designed for the job when she's more of the brains and manages the group, with the help of Urianger. EDIT: While all of them are scholars, only Minfilia and Urianger really have the time to do more research.

Keep in mind, the group Minfilia, Tataru etc. came from (which is called the Path of the Twelve, a group of people who posses the Echo) and the group of Y'shtola, Thancred, Urianger, Yda, and Papalymo (The Circle of Knowing) merged to create the Scions of the Seventh Dawn, hence why she seems so different from the rest of the notable characters in the group.

I'm meh about Minfilia but the reasons why people dislike her is just absurd.
