Now events have honor items and not much else to grind away. I suggest adding a boss (like the santa boss in the xmas event) that will drop the limited reskin of Mythic item. Limited Reskins for Mythic Items can rekindle player interest by adding a new aesthetic to mythics, making them feel fresh and exciting. These new costumes will give players a reason to revisit the game and show their progress expressed in a different way. Additionally, temporary offers will provide immediate and exclusive availability, encouraging players to engage and participate in the event. Everything will make for a grind and increase player count when events go live.

In addition in my opinion limited mythic items can help combat exalted inflation with the aid of introducing shortage. When new mythic items are released in limited portions, they invent a sense of value which can stabilize market inflation on some items. Players may be less in all likelihood to hoard exalted in the event that they recognize that in future they can turn them into profit as you wont be able to obtain it after the event or just to complete the collection.
