The pseudo-medieval settings become excuses for reductive characterization. But, that’s not the case for A Song of Ice and Fire (ASOIAF) and Game of Thrones (GOT).
Other female characters in the franchise are believably real women, that’s because they’re mothers and grandmothers just trying to protect their children.
Most of the female characters in the series aren’t capable of fighting nor have dragons to do their fighting for them, but they find ways to push through.
