They also come with ability to bend other related elements or other skills we can learn sometimes. Wterbenders can be healers and earthbenders can also bend metal while firebenders can learn to redirect lightning... Semblances sound interesting too ...So, in case where they are not element based, what are they then? Can they be anything?

I'm pretty sure anyone who learns them somewhere can do that. Oh, so we both protect the world then, aaaaand the rest of that sounds very familiar too. I guess our worlds aren't that different sometimes even if they can still be really different despite the similarities.
