Because it encourages people to come back to the game before Legion, and get involved now. Some folks hated WoD, and are just getting back into it. Also what everyone else has said. It will be replaced way before 110... I had a full set of 790s before 109 in the beta. Some were 800 or 800+ ... so a bunch of garbage that helps me level is much appreciated. Less shit to sift through as I level, Just sell all of the crap unless it randomly goes Epic.
