Well, shaped coral or iron rings, some of the amulets as well as all elder belts except for heavy ones arent selling all that well, even at high ilvls. But I've only gotten like 4 full sets so far that were worth doing the recipe with, so its definitely not a common thing. You could probably make profit buying low ilvl shaped/elder jewelry though.
I'm sure some people are doing that, just because.
In fact, I think some people are buying shaper/elder scarabs just towards that goal - get good shelder bases to sell, and if you don't, there's always the exshard recipe.
But, maaan, is it a drag or what. At least chaos recipe is an automatic thing - you only need to pick up items and maybe have an organised space in stash for convenient set assembly.
With exshards you actually need to spend time on trade sites buying the missing pieces for cheap, which means dealing with woops, competition and shitty sellers. Really breaks the flow of the game.
