I would like to correct a misconception that has been littering this thread, with regard to Korra's attitude/fighting style. It has less to do with defensive/offensive and more to do with her being a genuine water-tribe-born bender. Her style is insymbatico with the core of waterbending.. which is raw emotion. Whe she fights, she doesn't just do stances and cast out elements.. she vents, she rages, she becomes a purely emotional fighter. It makes immensely powerful, but also leaves her too open for counter-attacks and "come at you sideways" assaults.
