Unsocket recipe (w/out destroying gems)

i managed to make plague using the original plague forumla with a fal instead of a sheal a few season back season.

because its the only rw in the game that they have ever changed the runes to make it with.

but i dont like the idea… if it removes gems and jewels thats fine, but it should not be allowed to remove runes.

also if its a cube formula it poses an issue of where to put the gems.

if u have a 6 soc polearm with 6 jewels ( idk for some stupid reason, its to prove a point)
4 of them would fit in cube, but where would the other 2 go?
