With it taking 5 fragments now to get 1 rift key are you going to buff the loot off the Rift Boss since now it takes 5x longer to get 1 key?
Seems this patch made everything 2x or 5x longer to acquire things.
I can see why it might appear that it takes longer to gain entry into a Nephalem Rift after this change, but thankfully that isn't the case. As others have pointed out it actually takes a slightly shorter amount of time to gain access to a Rift. Previously you gained one Rift Keystone for completing 5 Bounties, but now you gain 6 Rift Keystone Fragments instead, and it only takes 5 of them to open a Rift.
In addition to that, we've increased the loot you get from Rift Guardians. They now drop more Blood Shards, and have a greater chance of dropping a Forgotten Soul. The goal, and what we hope for, is to find a reward pace that feels right.
