That sounds about right, although with infinite time to spend tweaking them I'd be tempted to make a separate profile for every conceivable strategy: JJ, Mystera, and Tikki Tooki for fireball power; GG, Taurog, and Pactmaker for resistance; GG, Binlor, and Tikki Tooki for CYDSTEPP; etc. Then I could also selectively unlock items as well, and perhaps even skip some of the tier 3 classes to avoid their glyphs, which should nearly eliminate scumming - at the cost of having to maintain half a dozen save files, of course. Not even arguably worth it until the game is less in flux than it is at the moment.
Anyway, I have GG and Dracul unlocked already and was hoping to find Binlor, but with the loss of Blood Power, Dracul is indeed a lot less useful than Pactmaker would be. Pactmaker's pacts are fairly useless with just GG and Dracul since they're so stingy with piety, but given that Binlor refuses to appear I might still go with Pactmaker just for the free +50 piety in every dungeon. Incidentally, I'm starting to think that it's impossible to get Binlor (or Earthmother or JJ) without unlocking Taurog, Tikki Tooki, and/or Mystera; none of them have made a single appearance.
