With patch 2.6.5, Diablo 3 has received 3 new torment tiers (14, 15, 16). As I was running greater rifts and normal rifts which match difficulty wise (65 = 14; 70 = 15; 75 = 16), I realised, that experience wise, normal rift are faaaaar behind greater rifts.
This made me wonder, what exactly is the benefit of the new torment tier levels? Do they provide more drops for certain items?
Please note that this question is more about the rifting aspect of the game than the other content, though a list of changes in other content is welcome as well.
