Yeah I completely agree with the whole "overpowered" stuff.
This is supposed to be based off of Avatar, and it clearly states that there is only one Avatar, and that you can't bend more than one element unless you're the Avatar.
Be creative! You don't really have to be a bender to be cool... Remember the YuuYan Archers? They were tight, and yet they couldn't bend.
Also, I checked out the site, and boy it was great. Don't forget to use the pics of our characters
Pic of Orinth should be on page like 4 or 3 or this thread. Too lazy to look myself
