>>93739113 If I had to guess, I would say it's related to her philosophy of causing the least collateral damage possible while doing good deeds.
That's what lead to her quitting The Avengers when they were taking down a group of villains known for their damage-causing.
She lives in Jersey, a hundred foot tall clumsy teenaged girl causes a lot of property damage in populated areas.
But that's not the case with a temporarily 12ft tall girl, and you see her turn into that much more often.
So she doesn't do that. Because she's considerate and cares about people.
