Why should they feel special when any lvl 90 can get any of them easily (with the exception obviously of the staff from Naxx).
Blizzard loves to throw around that whole line of "well you have the achievement with a date on it" crap as well so what's the big deal? Better to show it off in xmog rather than have a bunch of orange weapons that rot in your bank for the rest of eternity.
If anything it's spitting in the face of the people who DID get them when it was current because "lol those weps you have? yeah they're useless now enjoy them just cluttering your bank because we know you don't have the balls to delete them"
