In dom2 I always took Turmoil-3,Sloth-3,Death-3,Cold-3,Luck-3 (and magic depending on strategy), so I don't see that as changing much
And besides, it is being multiplied by 10, yes, but from what number exactly?
My tests indicate that their death dominion now kills 5% of the population per candle (and that population death occurs after dominion spread)
IIRC that's the same number it was in dom2.
