I recommend incorporating these weapon skins, available through a major, lasting PvE challenge.
Possible PvE Challenge Ideas
1. Design a new, or intensify an existing, high-difficulty World Boss, and include the skins in its loot pool. (Like what happened with Moltenus). If victorious, the boss randomly drops a skin, and you roll the dice for it.
2. Develop an enhanced instance for the server and integrate the skins into its loot rewards. Example: Padmarashka hard, Runadium hard, Makarna. Here, the final instance boss holds the skin. Once beaten, a skin drops at random, and dice rolling decides the winner.
3. Offer skins as extra rewards for tough instances (Runadium/SWB/Sauro 2K/Infinity Shard/Tiamat Hideout, etc.), with a minimal drop rate akin to the Tempering Box. In this scenario, winning a roll gets you a non-tradable Box to select your desired Skin.
4. A non-tradable crate could be added to all Atreia bosses, having a very low drop likelihood, allowing weapon choice as an extra reward. Roll the dice to gain it.
The visually striking skins will inspire players to tackle more demanding PvE activities.
Consider this, please. Appreciate it.
