I was playing (Classic) AA and rolled spy. When N1 ended without any maf visits, I assumed they were either rb'd or afk. But this lack of maf visits continued throughout the game, until I was ignited by an arso and died. I didn't manage to get a screenshot, but there were zero maf roles in the after-game lobby.
The spy's main ability is to see maf/coven visits. Without them, it's just a sitting duck on town's side to be killed. But spy can use bugs, you might say. Let's not kid ourselves here: bugging, on its own, rarely provides enough info (or even any at all) to sustain a whole TI role.
So for the sake of all spies in AA, only make it spawn if there's maf and/or coven to keep track of.
(Coding-wise, I think it would work the same way as how VH only spawns with vamps, so this shouldn't be too much of a challenge)
