Completely agree with a lot of the points being made here. I have no problem with new characters being introduced when necessary, but we still have so many characters to get through that it does not seem needed at this time.
And why is it that all of these new characters seem to be getting shoehorned into one or two factions (namely Preternian good guys) even though their style and names do not fit?
I would be a lot more comfortable with Spector's existence if he was a NA character and had nothing to do with the past.
If they were sprinkling in the occasional new character, say two a year, who were well designed, distributed evenly among the factions, and fit the style of the era/faction they were being introduced to, then great, I would have no issue with that at all.
