Unfortunately no.

There are still some nations without heroes. Nations that were not in dom2 are more likely to lack heroes.

MA Agartha gets their first two heroes in the upcoming patch. MA Mictlan gets two new ones. Marverni gets it's second hero.

While waiting for me to make heroes for all nation you can try the worthy heroes mod. It gives every nation heroes that are quite thematic. I believe it is quite popular.
