Hey there I see a lot of threads popping up on this topic so I wanted to stop in for a visit and explain the changes. The Kadala change is primarily meant to be a quality of life change for players.

Having to fill up your inventory and run back and forth to the blacksmith could be a mildly cumbersome experience and we wanted to improve that. All items on Kadala had their cost increased, when this was done the chance for her to give you items was also increased but by more than the cost justified.

For the same number of shards as before players will now walk away with 1/3 more legendary items.

Since we wanted this change to be purely better for players and we know that many people get their crafting materials from Kadala we also decided to add a lot of extra crafting reagent drops to Greater and normal Rift Guardians. The overall impact should be that you are getting roughly the same amount of crafting materials, except instead of getting primarily yellow mats like Kadala gives you, the mats on the Guardians could be white, blue, or yellow.

This should help even out the quantities of assorted material types instead of flooding players with just one type like Kadala was inclined to do.

We will continue keeping on eye on all the effects of the changes. If we find that these changes had any meaningful negative impact on the ability for players to generate crafting materials we will make further tuning adjustments to the amount of material dropped by Rift Guardians.

TLDR - You get more items than you used to!
