Do you realize Blizzard hasnt stated the final price of the legendary questline is a weapon?
I could be wrong ( i use to) but as far as i can remember official word about legendary always focus on the term "item".
The rest is community speculation and I know if they end up giving us a ...I dont know,legendary trinket some will feel cheated.
We got a legendary gem,then a legendary metagem...Im gonna laugh my ass off if the final price is a legendary bag of 36 slots or a legenday tabard with an on use that animates a little Thrall dancing polka.
No,really...is there anything more than thin air that suggest we are gonna get a weapon? any blue or any hint?
