Well the more I bother with the "legendary" quest chain, the more I realize how completely useless the journey is.
If my Sha-Touched weapon will become useless in 5.2, why the hell was I doing the quests for the Black Prince in the first place. I bet the final prize will be awesome, but in the meanwhile, spending over 30k gold on the (+500stat gems and sockets) to upgrade the weapons (LFR/Normal/Heroic) now seems like a complete and utter waste and I wouldn't have done it after the first gem, if Blizzard would come out sooner and say "hey, those weapons you have there, are only gonna be good until 5.2, where other weapons will be better".
I really expected maybe an upgrade for the said weapons or
a new set of Sha-Touched thingies.
