Ok, the 12 possible setups are:
And these 12 setups should be somehow balanced(Not exactly balanced, but no outliers like a 70% town winrate, especially on all setups combined)1. Mafia Goon, Mafia Roleblocker vs. Town Tracker, Town Cop, 5x Town Vanilla
2. Mafia Goon, Mafia Roleblocker vs. Town Roleblocker, Town Cop, 5x Town Vanilla
3. Mafia Goon, Mafia Roleblocker vs. Town Tracker, Town Jailkeeper, 5x Town Vanilla
4. Mafia Goon, Mafia Roleblocker vs. Town Roleblocker, Town Jailkeeper, 5x Town Vanilla
5. Mafia Goon, Mafia Rolecop vs. Town Doctor, Town Cop, 5x Town Vanilla
6. Mafia Goon, Mafia Rolecop vs. Town Doctor, Town Jailkeeper, 5x Town Vanilla
7. Mafia Goon, Mafia Rolecop vs. Town Rolecop, Town Cop, 5x Town Vanilla
8. Mafia Goon, Mafia Rolecop vs. Town Rolecop, Town Jailkeeper, 5x Town Vanilla
9. Mafia Goon, Mafia Goon vs. Town Doctor, Town Tracker, 5x Town Vanilla
10. Mafia Goon, Mafia Goon vs. Town Doctor, Town Roleblocker, 5x Town Vanilla
11. Mafia Goon, Mafia Goon vs. Town Rolecop, Town Tracker, 5x Town Vanilla
12. Mafia Goon, Mafia Goon vs. Town Rolecop, Town Roleblocker, 5x Town Vanilla
Ok.
First the Mafia Roleblocker setups(1-4)
Power roles: Tracker, Cop. The mafia Roleblocker cannot be roleblocked. It is of high importance for the mafia that the power roles die early enough. A tracker is in 2 of the games, so roleblocking is dangerous- if a tracker spots it and the other Power Role reveals itself then the Roleblocker dies. If the Cop gets a guilty result N1 with Tracker alive(or the Tracker with the Cop alive on N1) or if a Mafia dies early by lynch its near Game Over... for the Evils.
Power roles:(T)Roleblocker Cop
Clearly weaker than the previous setup. A roleblocker can target the cop and stop them(terrible) target the night killer(good) target the roleblocker who roleblocks a vanilla(meh) or roleblocks the cop(good). As long as Roleblocker does not stop the kill twice it is not giving the town another possible mislynch and it is worse than a tracker because the tracker always incriminates while the Roleblocker does not.
Power roles:Tracker Jailkeeper
The Jailkeeper can protect good people at the expense of their abilities or stop bad people. It is more flexible than the cop but also arguably not that strong.
Power roles:(T)Roleblocker Jailkeeper
Apart from these cycles that cannot be resolved via NAR we have two people who can roleblock. There is a high chance that one action won't get through... and possibly more as both roles are stronger at the end of the game.
(1-4) internal conclusion: There is some swing when setups differ, but it might not be that decisive. Win rate has to be found out by trial and error
Mafia rolecop setups(5-8):
Power roles: Doctor, Cop
Again, these power roles are quite strong and arguably Mafia has got the rolecop to find them fast before they run havoc. Still the Rolecop results cannot be used for killing before night 2!
The presence of Doctor and Cop makes a claim strategy possible. Large amount of what you call positive feedback.
Power roles: Doctor, Jailkeeper
If the jailkeeper has to claim then it can be protected by the Doctor. Although that only happens in a bit less than 50% of the setups its still a major concern for evils, especially with two protection roles running around. But this one has no cop so at least no evil will find itself in an untenable position even with good play.
Power roles: (T)Rolecop, Cop
The rolecop is a limited cop for the enemy rolecop... which means that the mafia power role is more endangered than the goon. The rolecop should probably claim if the other rolecop dies because they arent useful anymore. Which means that if the Mafia rolecop dies early you will have a claim cycle: "Rolecop claims plz". If no one claims Rolecop then there is a doctor and the cop can reveal... Or the... Jailkeeper, even(see above)
Power roles:(T)Rolecop, Jailkeeper
Arguably the weakest combo. Rolecop cannot see much, Jailkeeper gets more powerful the longer the game goes and (M)Rolecop can find out power roles
Internal Balance (5-8) Cop is better than Jailkeeper, especially when there is a Mafia rolecop running around and preventing the Jailkeeper from reaching later nights. Because Rolecop gets at least 1 result, and has definite knowledge of whats evil and whats not they are probably not weaker than the doctor here, except for the possible concerning combos.
No Mafia Power roles setups(9-12)
Power roles:Doctor, Tracker
These roles are not that strong like full cops and jailkeepers, but if the Tracker finds one evil then they might be protected by a hidden doctor... and then it looks grim for the Evils. On the other hand every nolynch could be met with a nokill, dragging out the game endlessly. And there is no (M)Rolecop or (M)Roleblocker to deal with these power roles.
Power roles:Doctor, (T) Roleblocker
A doctor can protect the roleblocker, if it comes down to 1 evil and the rber is alive. I am unsure how strong this combination is in this case, because they have at least 1 synergy: They both stop kills so 2 kill stops(aka 1 more mislynch allowed) are possible. In the unlikely event that the blocker targets the doctor who targets the victim the blocker is bad, but they are still useful more than detrimetal
Power roles:(T)Rolecop, Tracker
The Rolecop is basically a named townie here, except when they try to out the Tracker.
This setup is clearly worse than its doctor counterpart. No synergy possible.
Power roles:(T)Rolecop, (T)Roleblocker
No synergy. The unlikely bad combination is no more, but the power drop is still high. Same problem as above, except that Roleblocker is worse than Tracker except in a few MyLo cases(where you have one more chance as opposed to the tracker)
Internal balance(9-12)
Setup 9 is much better for town than setup 11 and 12. The same can be probably said for setup 10 as well(much better than...) The Rolecop/Doctor dice is clearly imbalanced when you have rolled Goon before. Obvious internal imbalance.
Roleblocker and rolecop are mitigators, they decrease the average effect the enemies have. I am unsure how this will play out Like I said its mostly trial and error anyways probably... as the setup knowledge is also a factor.
BUT
This has pairs of roles. The pairs should ideally be close to strength. The Cop/Jailkeeper difference is ok, even if cop is a bit better. You can't balance perfectly.
The Roleblocker/Tracker pair is arguably not equal, but the difference could -
The Doctor/Rolecop pair is... not so good. If paired against an enemy rolecop the difference isn't high. Ok. But against goon the balance is upset.
In the setups 9-12 we have a glaring imbalance.
Setups 9 and 10 are way, WAY better than setups 11 and 12.
If this setup is to be tested then there will have to be some changes to fix an imbalance there, but I don't know which way.
