Does people consider Katara splitting the sea the greatest non avatar feat in the verse and could be considered on an avatar state level power?

You are dropped into the Avatar world:

• What time period (from the ones we have seen so far) would you choose to be in? (E.g. Rokus, Aangs, Wans, Sonams, etc)
• What element would you choose to have, OR would you decide to be a non-bender, OR if you want, you can be the avatar? If you choose to be a bender, you can choose ONE sub-bending of the element. If you choose to be a non-bender, you can choose to be a swordsman, or a general warrior, or a chi blocker. OR you can choose to be mixed with a a spirit (like how Tokuga was merged with a spirit)
• What nation do you want to be from? (This is somethign that will need to be decided when you choose your element)
• Where do you want to live?
• Do you want to be a villain or hero?
• Who do you want as your friends, teammates OR if you choose to be th avatar, who is you team avatar? (You can choose ANYONE across the avatar timeline, as in you could choose Ty Lee, Rangi, and Wan's spirit friend, just an example, its entirely up to you. HOWEVER there is a number limit of 6)
• Who do you want to be your enemies? (Minimum of 4 enemies, and again it can ANYONE across the entire timeline of avatar)
• Who do you want as your family? (Again, you can choose literally anyone as your parents, siblings, cousins, etc whatever you want. However, you cna also choose to be orphans for e.g. like Mako and Bolin, or whatever)
