I'm denying this, but it doesn't mean we won't implement it in the future. Read below:
This is not something that can be added for just one move. This is a system that needs to be in place for the entire skill set of Earthbending and it would not work unless we redesigned all of Earth's abilities to fit this play style. We cannot just add instant counter / blocks to a move that's this easily without having some sort of reform to other abilities to balance the counter out - which then means the entirety of Earthbending needs to be changed. Personally, I would love Earthbending to be this back and forth defensive element, but as Earth stands in the plugin right now; it's not possible.
- Left open for further discussion.
