@arcus: he used it to stop ozai's attack in comet and he used it to beat CMan and it was a whole stream of water too. those are better feats than korra's nonexistent ones.
goals didnt stop him it was a lack of control over one instance.
no water can expunge fire thats what im saying, katara expunged all of azula's fire but aang with his rock defense got blasted by azula more than once. earth is more available so aang used it against ozai
earth doesnt magically help u dodge fire which was ur initial statement. in raw defense warth is good but water expunges fire which is even better
