Ballista is still alive, and the only people who continue to play are those who love the game for what it is. They don't need material rewards as an incentive to play. They play to have fun. Introducing "rewards" for Ballista would only temporarily interest people to play, if any at all. When the experience point reward were added to the Ballista system, it didn't invite any new players. Instead, it was just a nice end-of-the-meal tip for people who already played. Sure, the Ballista Royale (reward) sparked new interest at the time, but the majority of people stopped playing shortly after it ended. If people only play Ballista for some sort of "gain", then that would defeat the purpose of the game.
