I like the undead crusaders. I also think its an intriguing idea to connect their return from the graves to a certain event/history like a plague or something special.
Teutonic knights per se are not planned yet. What we are discussing right now is the visual/lore differences between the human factions. Its pretty likely that one of these factions will have a very “knightly” style.
This topic is still heavily under discussion, so nothing set in stone here.
