Fixing Aranessa would be as easy as giving the Sartosans to everyone else in Vampire Coast

Just crank them up a tier on the ports (and Maneaters to T5) but leave 'em where they are for her faction, so she gets them "early" like Alarielle and Sisters of Avelorn.

Then put some bonuses for them in the regular Coast Red Line so that they can be useful for everyone, not just one lord.

Boom, a lot easier than creating a tonne of extra faction-specific reskin units and then trying to balance them in. Also means more time and resources to spend on updating the faction, because _damn_ they do need some updating. Or at least letting me attack from the sea!
