Assuming all albums are civs, which it sounds like based off "The good news is that the rest of the albums have banded together to keep the music of Rush alive," when a live album is the day, albums with powers should take a tiered strategy towards PMing for their power. This will allow us to have the most helpful specials receive their power while also giving civ specials solid information about other civ specials out there that could prove helpful.
How powerful your special is will determine when you should PM the mod to get your power. People - if you think I missed a power that's fine, probably not best for people to start listing them as it could help mafia find civ specials. If I didn't list your power, use your judgment for where it falls.
Obviously this isnt an exact science but if the round is 2 hours, and starts at 11:30 and ends at 1:30, the following roles would PM at the following times:
Cop - 11:31
Angel - 11: 45
Watcher - 12
Tracker - 12:15
BG - 12:30
RB - 12:45
1-time Immunity - 1
Vig - 1:15
If the tracker PMs at 12:15 and gets his power, he'll know it is highly unlikely we have a cop or angel out there. If he does not get his power, he'll know there's at least a stronger power out there than he is. And best of all, only civ specials will get this information so they can use it how they see fit throughout the game.
