Now that we can unlock Renown 61 and 62, they include Soulbind Upgrades for 2 of the Soulbinds, where the first row of conduits are enhanced.
According to First Row of Enhanced Conduits Unlocks Today - News - Icy Veins, an enhanced conduit increases the item level by 26 and its effect is increased by 2 ranks, compared to a standard conduit.
Is this implemented in AMR yet? from what I can see, the conduit on one of my specs that has Dreamweaver as the Soulbind is still showing the normal conduit value in the first row of conduits. Is that just a UI bug, or is it still using the normal values in your simulations?
