As a DH i can make around 3.5bxp/h spamming act 1 bounties for caches. It isn't as much as running Rifts but, it racks up keystones really quick.
Yeah I can spam T6 rifts pretty quick but make about 800m/hr more doing A1 caches. Depends on if I can get 2 or 3 others with me on rifts on which is better. Sides with the 100% T6 cache drop it's nice to be able to pick up 20 boxs then open on whomever I could use a new ring on.
