In the end though, there is no reason for it, because all contents should be of in-game format, like Garuda.

The only difference I can see is that the winning result for Garuda was determined by an in-game condition, this one is not as its picked by the reps. So to avoid this just make it done in game and have the game randomly pick a winner XD or something idk, you lose creativity wins then.

Maybe there is no way around it (though yes, lots of other game companies get around it, so idk what SE's business is)
