Hello everyone 
You bring up a valid point about the conduit upgrade items not being specialization specific. It can be frustrating when you get a conduit for a spec that you may never use.
To address this, we’re working on a change that will go live with next week’s restarts that will allow Soultwining Crescent and Death-Bound Shard to grant conduits based on your current specialization instead of by class. In order to receive the conduits of the spec of your preference, you will need to switch your specialization fully, changing Loot Specialization won’t work.
In addition to this change, we’re increasing the drop rate of Death-Bound Shard when completing Adamant Vaults in Torghast, Tower of the Damned.
Thank you for your feedback!
