A concern I have in running Polaris is that the group I intend to run the game with possesses RPGers of vastly mixed ability with regards to the skills used in the game. Three of us are veteran role-players but of those one of us tends to do very poorly in exactly the kind of verbal exchanges that Polaris's conflict system is based on and the fourth player is still very much a novice with regards to RPGs in general and often has trouble coming up with ideas rather than choosing from a set of options. All of us are on board with a character-focused low-plot catharsis-driven RPG, but I am worried that a massive difference in rhetorical ability between the Heart and the Mistaken will cause two of us to break tragedy into its opposite, the epic, while the other two break tragedy into its flanderization, the grimdark. This is particularly undesirable because it will result in two of the characters dying long before the other two do, though that may be less of a problem in Polaris than I expect. How can I prevent this discrepancy in ability from unbalancing the game and creating a disjointed narrative?
I could deliberately hold back as both the Mistaken and the Heart and discretely ask that the other skilled player do so as well, but I think that would make the game much less fun for both of us because it breaks immersion.
