Patch 2.0.6 is now live and will require a client update for the game to be updated.
Notable changes include, increasing the drop rate of class specific legendary items. Improving the monk class legendary stats and removing the requirement of a crafting material for crafting.
Crafting material will no longer drop and old ones will be greyed out and have a higher seller value to the town vendor.
This should help alleviate the constant game refreshing which many players resorted to to find a specific crafting material but the removal of the crafting material is something that is something that I think could have been repurposed to something more useful - perhaps we'll see something further down the road which will incorporate them back into the game.
