True, but waterbenders don't get that ability until 4th level, indicating a decent level of proficiency. Plus, it allows better movement on ice and snow too (a major benefit when one lives at the pole), allowing maneuvers like this
. Finally (and I feel slightly silly saying this), it fits the pattern of the classes. Waterbenders need some sort of movement ability, and a ski ability seems to fit best with the evidence provided by the show. However, I'm open to alternatives.
