I think you make some good points there such as the first five( but it is early and the Swiss and Burgundy as true powers didn't come around until late).

Most of the units will be evened out for the proper release. The Ruthenians were a people around the Medieval ages and king Koloman of the Ruthenians fought with the Poles at Liegnitz and threw a Mongol rider on horseback over the bridge( He was a man known for his great strength)
I'm sorry about the viking potraits but if they would have been in the mod, it would have been HUGE(Almost twice as big, try having a look in the Alchemist Lab and i think i've done a BKB mod thread. That has additional info about problems with the Beta.

I don't use the Gnome editor, so i have no idea what the problem is.

Thanks for the feedback, the English, Byzantines, Danes and Germans will all be strengthed accordingly for the official release.
