Yep. I was disappointed aswell. I dont think they should remove Heavensturn, but atleast make it something different. If their problem is not enough time to create another event, maybe turn Heavensturn into an event where the player has 2x exp, higher item drops etc, something that only requires them to either add or reduce the amount in the game.

The helmet being the only reward, instead of a emote or an outfit, doesnt help either.
