Its a matter of having the right himes and maxed grids, with wind people are doing over 1M easily since exceed + aether, same thing with thunder cause aphro, water i suppose that grid + ashy, my water isnt up there but alakah, non and some other dolphins hit over 1M like nothing, for dark i know that mlw hits cap etc, all of them find great value out of exceed, its just a matter of how advanced is your grid, you can ask them yourself how they get that, and all of them are just casual spenders or dolphins, whoever you prefer, they arent galactic whale territory where madnug superxham etc lives.
