Because their "Legendary"......
Need to look at the 4 capes, like for the mages you the Demo/Necros will not want the HoX cloak.
For the tanks, can't see the Guards/Conqs trying to get the +magic damage.
And for the Rogues, Barb is not going to want the +Dex and the Ranges/Sins are not going to go for the +Str
And the healers, the PoM/ToS won't get the +2hd combat rating and the Bear won't want the +magic damage
Yeah, you could get all 4, but most people really only want 2 on their toons

Aerion Brightflame. One night, in his cups, he drank a jar of wildfire,
after telling his friends it would transform him into a dragon, but the
gods were kind and it transformed him into a corpse.
