On national thematic pretenders.
Some of them have a 10 or 20 point cost for new magic paths so they're ok for me, they're supposed to be versatile mages and that versatility is there to be used (i.e. Mictlan's Smoking Mirror)
For the ones who don't have an easy access to other paths, and have just the national paths, maybe it could be good if they start with an already quite high magic power on them.
The idea is that even if I take them the way they come without boosting their magic, they're already mages that the other national mages envy and respect fort their knowledge of the magic they study. Dunno, like having 3 or 4 on their paths, so the "national flavoured" blesses and possibilities to cast the national summons and spells come easier for them.
I think it's thematic and logic and would fit nice on the image of a pretender with the magic paths of his nation - as they represent IMHO the deep connection between a nation and its magic paths.
This possibly unless they do already wondeful SCs by themselves
