Furthermore, I think we should all get something kinda rare. The legends could get a certain piece of the artifact, while all the other tiers get different pieces as well. Non participants could get some kind of, I dunno "token" or something. Anywho, you would have to collect all the parts of the artifact to create a full artifact. And maybe said artifact could do something special OR just to say how awesome you are at the Feats.
ALSO, maybe re-package the Projects badges as Feats badges and then we could get badges for this stuff :D.
Just a thought!
