Devs added Legendary ingots as a carrot so tiers 3, 4 and 5 became much more interesting to buy.
But now with Delve, we have another ressource to get these Legendary ingots…
So these Legendary ingots are not that much interesting now, so I guess we need another carrot.
Why not replacing the ingots by Chaos Shards?
And related to this feature request, could some Chaos Shards be added to the Event rewards? As we are destroying Portals, it should be normal to get some shards from these portals .
