I dont like question B as I feel its somewhat a "How much time do you think you'll spend strategizing" question rather then just activity. Thus my answer is the bare minimum I can say: I will not be inactive.
As for question A, I am in a weird predicament for them, but as non-mafioso, I do NOT mind mass role claiming this mafia. This mafia has some hard to prove roles and their are plenty of vanillas, I think mass role claiming wont be as damaging this mafia compared to the rest. Where Joey's hosting is sucking right now, his roles are really well set up tbh and fair.
I dont think we should waste abilities, especially One use ones. Not knowing if their still their or not for mafia's sakes makes them tip toe still. I find it equelly damaging to cyberman Tenant as I do to see abilities wiped out. Especially matts, like if he gets cyberman'd then whats the point of his abilities? I also strongly believe that the cybermans ability works as a lobo+antimatter type of effect since civvie abilities will help civvies, not mafioso except tennants. But lets say that Tennant is cyberman and keeps his ability. A mafia member dies and is role flipped (none of the mafioso's abilities stop the role flips from being seen) Then tennant brings him back to life. We already know they're mafia, so we just wipe him out again, no big deal except that it took 2 days to kill one person rather then 1 but also gives us tons of information: cyberman has been used. Then townies dont have to worry so much.
I strongly disagree with wasting abilities, especially one use ones. Everything should "have a practical use" does NOT equal waste all you're abilities.
