Here is the problem with them in the loot table. If you look at the what the vanguard sells there are 3 ghosts, look at what shaxx sells there are 3 ghosts. They outweigh all the other loot for that simple fact. And to the guy below, 310 guarantee from iron banner, totems check point will get you a high level ghost almost every damn time you do it as well. They have zero purpose in the nightfall. And I refuse to spend anytime doing the nightfall ever again until they are removed.
