@Lord Tyrion I assure you that nuke sniping was definitely something that happened, and bots were not used. That being said I think you're right and the game should be more clear about when a nuke/missile is spyable, nothing is more annoying than a person basically spy slotfilling someone because they don't realize the nuke is protected.
As for pre, perhaps buff spy vs infra? It's literally so bad that it's a meme, so maybe let the spy kill some infra and a random improvement (excluding NPPs). It wouldn't make it overly strong, but it would give the function some use.
