And you're going to have to get used to the fact that the shared universe concept becomes a cynically applied conceit when it's permanently set to selective one way traffic mode.
Not one single person in this thread has argued that the variety of Vibranium that's been part of the Wakanda mythos from day one originated anywhere else but from outer Space.
What's been clearly enunciated by more than a few posters is the fact that the discovery of said Wakandan Vibraniums original source should have been tied to a Black Panther-centric book or storyline.
No one currently posting in this thread was responsible for the last Black Panther solo being cancelled just as David Liss was incorporating Shuri and Wakanda into the ongoing narrative but there's no doubting the fact that said cancellation provided the necessary vaccuum to facilitate the nonsense that occured in AvX
and I say this because there was zero evidence of T'Challa and Ororo havinf to seek the guidance of a marriage counsellor during David Liss's Black Panther run.
Choosing to be willingly obtuse to the fact that core elements of the Black Panther Mythos and associated lore are being systematically strip mined to lend weight to other characters and books, and then falling back on the straw man argument that all's fair in the absence of Black Panther scribes having not explored this avenue previously totally misses the overarching point but as you eloquently stated previously.....this is the internet.
