I very strongly disagree; I think looking at the role names themselves ie. "Roleblocker / Rolecop / Rolestopper" and assuming just due to those names they're more likely to be mslynched is a bad idea and the wrong way to about reviewing here, it also ignores what happens and how massclaims are handled during the game.
Mafia have a night kill and they know which town claims are truthful or not is not a logical argument to "Mafia don't have a lot of leeway in this setup", it being a normal game doesn't mean that mafia should be expected to fake claim VT at all (How you're attempting to use that argument to differentiate Normals/Themes is ???) it merely means that there's a restricted pool of roles inside the game and mafia are able to fake claim inside that pool, the problem is with this specific division of town roles mafia won't ever get away with a fake claim. Like while the setup is 'normal', this isn't going to be a typical game in that mafia in this game will outright lose if they fake claim here; not something that's always the case at all.
I'm not assuming that town won't ever mslynch a power role, that's absolutely not what I'm saying, there's every possibility that mafia get the doc considered as a 'clear' town mslynch a PR Or two and mafia just move and win the game, this isn't
unwinnable
for mafia as a setup, I just think it's stacked too heavily against them with the sheer number of power roles inside the game where all of them are 'relevant' throughout the entirety of the game.
Like just think about it for a second, if mafia ever get down to 1 member, roleblocker & motion become very strong. I think this setup could turn very snow ball-y in the towns favour with just one thing going their way early on.
