I am afraid that both those arguments contradict each other. Either they are an active participant, and thus don't need us to go there teach them (the witches are here after all), or they aren't, and thus we should focus first with active collaborators.
And I mean, I am totally in favor of helping Kislev, I just think that by priorities we should do Laurelorn first and then Kislev on the following turn. Ot os not that much difference in what gets done, this being long term stuff, but it is something that matters to the politics of the project.
