Thank you for leaving your feedback. Unfortunately, we don't have a specific reason why snipers were given jet packs. This is just the way that we designed the kit. Because the event and thus the minigame is currently over, we can't change that. This would mean that we additionally can't accept or decline your feedback.
We will, however, take your suggestion with us, for potential but not guaranteed future use during discussions in regards to Star Battle. I will add a feedback label to your thread and relay the information to the team. If you have any questions about this, please don't hesitate to reach out. Regardless, I wish you a wonderful day
