There were bits and pieces of information:
In the current raids, you obtain the recipe from the raid, but he materials to craft the recipe are obtained in the field. Through use of challenge mode and other forms of hunting, you were able to easily obtain large quantities of materials, but the recipe was obtained via a low drop rate. It’s possible to immediately get finished crafted items in Velcoffer cubes, but these were untradeable, which resulted in the majority of them being dismantled into materials, making no significant difference.
In the new unique raid, you will be able to obtain legend materials, unique recipes, and tradeable crafted legend items. In addition, the process of obtaining the materials to craft these recipes is shorter than before.
Notice how they said, “these were untradable” implying that they are not untradable anymore. In retrospect they could be also referring to the fact that Velcoffer cubes don’t exist anymore.
But then the second statement implies it again:
The tradability of finished products obtained from Legend Raid cubes will remain unchanged.
This should be referring to the old Legend Raid cubes, so it was safe to assume that the new drops can be traded, or it makes no sense to even point that out?
