She doesn't do every fight the same way, she just solves every problem with fighting. The issue here is she's shit at everything, EVERYTHING that isn't fighting or related to such. You'd think she'd be the best PC at fighting if that's all she can do. She's constantly outmatched at the one thing she's good at because odds are always stacked against her for no reason. 

Like that fight with the Sea naga. She was perfectly healthy, using her favored equipment, in a one on one fight. She should have by all rights won, but she wasn't 'supposed' to. And wings, automatic strength advantage, sharp teeth, durable, mageblood for damn near all of them. They're broken.
