Hmm, didn't you wish to have something more freeform?
Wouldn't this clash with the idea of having hard set locations?
BTW, here's a full map on the Old World:
My problem is that WHFB map is a bit too linear and doesn't focus on anything aside from not!Europe.
If we can remove Nagash corruption as a must for example we can gain plenty more freedom.
Currently as I chose Araby I'd be hard pressed to ever capitalize on the actual benefits of my nomad cavalry.
If possible I'd wish to have borders with the Empire and its allies.
