Heh, this thread is a REALLY nice indicator of people's various playstyles.
I reckon the pacts are acceptable as-is ... but yeah, Consensus is hardcore valuable in a lot of situations and it's my most common takeaway from the Pactmaker, too.
As far as common Pactmaker "partners" are concerned ... I find Earthmother to be a pretty good one. By late game, you can easily have 30 piety "spare change" once clearance becomes too expensive. At that point, grabbing Consensus can mean one extra Clearance at most, and most of the other boons have probably been maxed out in practicality too. At that point, Scholar or Alchemist are excellent investments, and with a little forward planning the others work nicely, too.
Scholar is most effective not when you want to avoid a 1-hit KO, but rather a 2-hitter: if you cannot survive a single boss strike with your vanilla stats, you're better off spending the piety on more responsible things like resistance or extra HP.
