"Resonate says:"Earthbending is cool....but Water bending is definitely the most practical and what I would choose lol"
Never! Earth is everywhere. Only certain skilled waterbenders can pull water from the air."
I don't know if it's so much as skill as it is knowledge.
Waterbending isn't the most practical since you need an adequate source of water, but it is the deadliest. Anyone else notice that Firebenders aren't very creative?
