First of them provides to pet the ability to picking up the death breaths. Second pick and salavge non-legendary items, but neither gives ability to pick up other crafting materials. I think it must be changed and this should be added to one of them.
There are some threads about this.
I think we have to wait to know if the PTR will be extended and/or the final patch notes.
Amongst other things this came to my mind a couple of times since picking up the game a couple of days ago as well.
Extend the “Carrior” node of the ancient stone to the other three crafting materials which are dropping, namely: Reusable Parts, Arcane Dust and Veiled Crystal. Since they don’t have to be salvaged and Deaths Breath is already a crafting material “Carrior” fits better than the node called “Husk”.
After the season ends such a functionality (picking up/salvaging automatically) should be transfered to the off-season realm/characters.
Problem: With speedy builds the pet doesn’t keep up with its task of looting. The player, which is interested in getting all loot collected is forced to slow down his running speed or return to the same locations again.
Solution: Grant all (also off-seasonal) characters (e.g. after completing a GR 75 run solo) an option (on/off switch) which allows automatic looting (and optional salvaging) of all loot (including gems and legendary/set items, which are not salvaged).
