I think it would make sense for earthsmash to have a similar charge effect as shockwave. Falling from a height would create an earthsmash, if the player is looking at a source of cours.
Then the same goes for shockwave.Oh please no. I can see it already.
Catapult away. Raise an EarthSmash instantly. Ride the EarthSmash. Then raise another earthsmash for you confrontation. Shoot it. *Then some actual fightning happens* After a while... Catapult away. Raise an EarthSmash AGAIN... etc.
I think this would just take the point away of charging earthsmash if you can practically just keep making earthsmash s WITH earthsmash s or a simple catapult...
Also I feel like this can make earthbenders a bit too similar to airbenders.... Earth should be deadly- but not for the wrong reasons. You can already carry an earthsmash while catapulting if you have great timing.. (While this does take skill, it's too rewarding) So pretty much earth has the potential to be like an airbender that loves to spam airburst after falling. (The element is called earth for a reason. Earth shouldn't get such a good damage output after falling or while in the air)
Shockwave isn't so bad.Then the same goes for shockwave.
Don't get me wrong, I love this idea. Its canon, it's realistic, and it adds utility... but, earthsmash's utility, mobility, and dmg is just too convenient for a simple catapult or other propelling move activation. Earth waits for the right moment to strike while sucking up dmg.Then the same goes for shockwave.
