Sorry about the wait, I spent the weekend working in the house and then was at work all day.

I agree, in ALTA the niche bending seemed like a really cool special thing, especially lightning bending which was something that so few people could do, and in LOK it was definitely overused. I still think LoK is better than the original, but that's something that ALTA did much better.

I like the idea of having benders who use two different types of cuffs, it adds another level of versatility and personality to the styles. As for era, hmmm, perhaps something more modern? 

Maybe we could go with something like there's some evil force that needs sealed away, and all four elements are needed to seal it. Our four characters could be chosen because they're the top of their classes or something.

As for elements, I definitely want to take air. I don't know if the character will be male or female yet, but I'll probably use leather for their cuffs and have them wear them on their ankles. They'd use their legs more for bending, possibly because of a bad shoulder.
