Not sure that they did this intentionally, but this campaign is going to give them some amazing data, almost as if they were A/B testing. On the Reddits, there are constant debates over whether the audience for CR is there for the combat which is reliant on the D&D engine, the S class worldbuilding reliant on the DM or the characters reliant on the acting/improve of the cast.Despite hating D&D combat, it looks like the soldiers table will be the place to be. The players, characters, and the dynamics are the least distracting.
C4 may really answer some of those questions based on viewship/completion numbers around the episodes. And honestly, the way the groups broke out, if you gravitate towards one of those three pillars, you probably have the cast you'd want.
Sam, for example, is a master at D&D combat, and his quick wit also helps enliven long encounters.
