Here is an out-of-the box thinking/theory regarding the game setup.
What if....the game was a dual between 2 wizards that could only use summoned beings (1 sk, 1 doc, and 1 seer).
That would be 5 power roles and 7 plain townies.
For example...
Pro-town: KevinH
Self-Aligned: EM, AoD, SJ
Mafia: Mole
That would explain why there wasn't any nk for 2 nights (ie. no sk to do the killing) and explain why no counter-claim on SJ or Mole. It would also explain why there are so many "self-aligned" roles.
good thinking out of the box. though why put mole in the mafia?
I think that is a possible set-up. A duel between two wizards would fit the theme of the game. My only problem as you've said is that there would be a lot of power roles. Given that we've had proven self-aligned SK and Golem, proven pro-town Vig, and role claimed pro-town Cleric, Seer, it would seem that by parallelism it implies that there is a self-aligned counterpart of the Seer. Only then would the battle be even. Otherwise, whoever is controlling those self-aligned would be too powerful. Don't think Narsis would create an imbalanced set-up.
Who is the Controller, the Seer's counterpart, and the Controller's counterpart? It would be a lot of power roles but then again this is Mage Wars after all. Zany as it seems but from everything we have it all fits.
