For ATLAstuck, I usually go with Jade as an earthbender, Rose as a waterbender, John as an airbender, and Dave as a firebender
I usually go Jade-Earth, John-Air, Dave-Water, and Rose-Fire!
Now I know what you’re thinking, “But Rose has a lot of water symbolism going on with her and Dave is basically constantly surrounded by fire imagery!!!”
And you’re right! And you know what? They HATE IT. Dave says explicitly that he hated LoHaC, and Rose DESPISED LoLaR. Dave hated Texas’s oppressive sun and heat, he hated the lava, he hated being surrounded by things that were hot and sharp and dangerous, he didn’t want any of it, and he really only found peace after he was removed from situations where excessive heat and fire were the daily grind. Rose might not have had anything in particular to say about the river that ran under her house, but we know that she didn’t like her planet, that she eventually went “FUCK YOU” to the idea of playing the rain and blazed (that was a pun) her own trail. Her really, truly big moment was when she created the Green Sun, a GIANT BALL OF FIRE, and it was that giant fire that allowed her to FIX things, to forge (that was another pun) a path that she foresaw as fortuitous, she’s a Light player and their symbol is the sun which is also fire, Rose has a fiery personality. Dave, by comparison, is much more willing to go with the flow (pun), and water is also an element that is heavily associated with healing, especially in the ATLA universe. Rose needs healing too, but I tend to think of her personal needs as closer to melting her icy heart that was embittered and frozen over by her upbringing, she needs to be loved, to be warmed, to let her inner fire shine. Dave is someone who needs to be soothed, to be gentled down, his healing is more focused on washing away the pains of the past and growing anew.
Anyway I literally think about this SO MUCH so I got kinda long winded there whoops.
