Firstly noob casual people, they have a lot of max level characters. I think your forgetting that people that cannot raid look for alts to fill something, eg "nobody wants a X, I'll make a healer, zomg they nerfed warlocks, I might as well make a hunter, zomg dk's get free epics" ... those boe epics have to go somewhere.
