I absolutely love, love, love the ability to rocket jump with the Fireworks Launcher. That said, the rockets and explosions are server side. Because of that, rocket jumping can feel very inconsistent. If it was client side, I feel that more people will be able to enjoy rocket jumping.
In order to launch your character into the sky, the server needs to know, so it’s not possible to make the weapon completely clientside. But we’re optimizing the weapon system and resolving more prediction errors that can occur.
