I've argued much the same but people keep tell me but then you'd be a kingdom without territory. But unless you leave a kingdom and take the fiefs with you how else can you capture a town with only 100 or so men? Yeah TW really doesn't think things through sometimes.
Which is fine, but again if you want to capture a town without having to join faction or outright buy it that's really the only way.
Looks like the perk has been moved to 300 in 1.5.4

Its not unreachable in a normal way, but would take ALOT of time and at that point Khuzait probably rule the world anyway.![]()

With the herd movement penalty in effect even for horses it's not a very viable method now especially if you have to get to 300 trade in new campaigns. I hope they rethink that requirement.
Yeah I guess having fun isn't allowed in this game.
