For me,I will not sell my crate now because I have spent time around 3 months when I can sell it for around 9k but now only 8k.Tho,we haven't heard official annoucement and information about how those special crate drop or craft and the most important is about the new Arcane pet.We haven't heard anything further about them.So let say Shady and Surge can be loot from normal crate,then crate price will go up.
