So, I was just watching the Order's liberation of Ba Sing Se, and I just thought "wow". Bending up to that point had always been mostly realistic (as realistic as bending can get), and its weaknesses were shown and exploited. Then the Order attacks, and their powers are somewhat akin to Gods. Iroh blasting through the wall with a single blast, Jeong Jeong floating in midair and creating walls of flame, Pakku creating localized tsunamis; it was amazing. I know the fire can be attributed to the comet, but all the Season finale bending seemed to be on a whole different level to what anyone else was capable of.
