I think that white gear scarcity is one if the bigger issues of the game. I also like Summer Sting as a two-handed weapon. And, prefer to use the Crestfallen Knight set. I have farmed these items for 1-2 weeks for several hours a day and have found approximately 5-7 of each - with targeted farming in specific realm states.
We all want to use specific gear and items, whether it is for aesthetics such as visually pleasing armor or mechanics such as a satisfying attack animation on a weapon. (I do wish Summer Sting didn’t have that pose at the end of the attack chain, it locks you in position…).
One of the suggestions I made a while back was the Deconstructing of gear. Basically, if you find a specific item, you can deconstruct an item for the recipe so you can endlessly craft it - provided you have the required resources. Removing the grind for farming the item and instead we can farm more resources; which is easier.

The post did get reviewed by the devs so I have my hopes up for some changes solving this issue in the future.
