Staff can view things that people equip, so if someone is back to back equipping flash grenades and they're getting reports of someone spamming them, they can be told to stop. Don't forget that birds also have a perk to shit nades so if it's triple xp time for birds and they ALL have the perk... yeah you're going to get flashbanged. The item suggestion for sunglasses is pretty nifty though. Perhaps a future Battlepass item...?
