The problem really is it takes ages for the equivalent pop to generate with DLU tokens (usually at least 8 hours) whereas the myth tokens spawn fully in a shorter time. This makes Erinyes in particular way overpowered.
Much as I like the two players who went from TF to FN, counting them as 'their best' is ridiculous. There's a reason neither player is welcome in True Fear any more.
I agree with your analysis overall though. FN failed to get their boots dirty enough early on and that's why they ultimately failed.
