Hm it would probably need too much effort in dominion 2 and more important unbalance it but what would you think about that for dominions 3 :

Pretenders have various stages :
They start weak but the more successfull their struggle for supremacy is the stronger they get .
It should be connected to dominionstrength :
You have 2 or more stages like the eater of the dead .
You start with stage 1 which is the weakest . Once you reach a total dominion strength of 50+ you get to stage 2 forever . If you reach a dominion strength of 200+ you get to stage 3 .

In each stage you get depending on your pretender stylish and thematic improvements . A VQ e.g. could start with recuperation and when she advances to stage 2 recuperation gets replaced by immortality . At stage 3 you get an even more powerful vampire queen with e.g. +x to attack/def/mr/hp etc. .

Human rainbows could get +1 to all magic skills with stage 3 e.g. . The "Monsterpretenders" like the Moloch could start as a small demon as they do atm and finally transform into an archdemon ( not one of the current arch demons but a new type ) .

This would make earlygame war more exciting too . I think atm your best bet to win a "normal" earlygame war is by attrition if the enemy has a sc pretender of his own , especially a vq .
