As for Blood nations I am not sympathetic.
Frankly I would gladly play Abysia under these rules. Even without contracts Blood Nations have some of the best summons going, and they have excellent national troops which will be much more relevant in a game like this (hopefully).
Also Abysia does use gems for a lot of stuff too (forging and summons) so its not like other nations have some kind of advantage if there are more magic sites
