I thinks the stands are a very fun one-time usage role, at least I had my fun using mine and considering possibilities, also trying to get killed so it actually works.
Mafia knowing the roles does help a lot to claim, but you still get those naughty townies like demon making mafia life harder and claiming things they aren't, still it's a good advantage and we even get to know sanities, makes planning become a bit better in terms of seeing balance and having a breather from having to guess roles, concentrating on giving names to the roles on the list. Could be fun to see other teams as mafia play like this and see how they'd fare too and how this affects mafia planning overall.
Town knowing numbers also help balance the fact mafia knows roles, I just think a death miller in this case wouldn't matter much because if you're giving them the numbers, they'll know immediately it was a death miller and not a mafia member that has died, and imo Death miller should be there to confuse a bit town about mafia numbers. But I see you stopped the count middle-way, so it's fine.
Inigo Montoya... How about next Gry game?
Troublemaker worked pretty well I'd say, in cases in which people are confused on the day's lynch, it opens possibilities, it can both work for town or mafia depending on lynches.
@Maryxxi you did a great job using that assassin right as I was killed so we got a kill out of that day and no bad side-effects from my burden role.
