It is very nice to be able to get fun world items as heroic loot from Delves. Sometimes the items you can get in open world content or Delves can be quite nice, but it is always outscaled level-wise by Mythic raid/+ content. However, since we will be able to get Dinars at some point in the season, please allow them to ALSO purchase items that you can only get in Delves.
That would allow those weapons to go farther and if you make a really cool one, allow players to max it out like any mythic weapon. This would not create a balance problem, since anyone getting an item through Dinars is going to have to upgrade it the same.
I would really like my exploding mace at some point because it is very fun with a nice graphic on PTR. Machine Gob’s Iron Grin
