But during those 2666 dragon runs i will also pick up a bunch of other useful gear and silver and shards :)
Maybe as trips said it is because i am ftp that i do not get it- its books i most want.
Oh of course. My point is that if you are specifically looking for one specific item, it's far faster to get it through chaos ore than it is through farming.
But a more useful example would probably be just farming for legendary speed set items in general - in which case, rather than 2666 runs, you're talking about saving 444 runs.
