It may not be a super winning strategy, but its a factor in choosing scales, if the impact happen to be quite significant on types spawned it may tip the balance of decision btween Turmoil/luck vs order/misf.
And for all your help / data, I'll share with you one of my favorite void spawn that I think many overlook (and it is also a reason why I obsess with void gate in addition to the fact that it's just cool), I've PMed it to you, I'll post it to the public once I'm done with my current MP game playing as MA R'yleth
I just hope I get it so I can use it...
Also LA R'yleth spawns void monsters in all their province with dominion, so the impact for LA R is potentially significant if you can make more void monsters spawn (also important long term when you loss your population and have no income). I've played LA once with luck scale and enjoyed getting random batchs of void monsters.
