I'm not sure what to make of it but in the game Pan cast GoNB it had huge income. It controlled ~ 1/3 of Sharivar, had dom 10 and got IIRC more than 10K gold per turn (perhaps closer to 15K but I prefer to err on the side of caution).
With GoNB it was invincible. 30+ PD everywhere + patrolling pans, endless centaur swarms & much more of every goodie that money can buy.

I've also cast it in an SP game as Marv. in Lands of Lore map controlling ~ 1/5 the map with dom 10 and the GoNB has more than doubled my income although I don't have good dom score.
