Upgrading Tribes as a Feudal with Reaper's Due?

[ZivDero]

With Reaper's Due out for several days, I've noticed that you now need tribes to have a lvl 4 Hillfort to upgrade them even for feudal leaders again. So I have almost all of Pannonian as Greek Orthodox tribal rulers and I can't even make them viceroys. That's annoying since I can't upgrade the hillforts because the land does not have the tech to build them. SO what do I do?

Make sure the land are under duke-level titles, at a minimum, so they can start gaining tech. Then, just keep building those hillforts and hope they tech up within a couple decades.

There's a problem with dukes. I am playing as Byzantium, so I don't want any Doux, I want Strategos (Duke-Viceroys) and probably an Exarch (King-Viceroy). Also, If you get noman land and don't manage get them upgraded they'll just defect back to them upon succession.
