yea its a good one. Honestly people want to min max but the difference on the battlfield is neglible.
That was a joke answer lol. spooky nightmare drop from overlord. Dying that would be a crime lol. I would however be riding around on the biggest money pit in game. paid 15mil for the mare then whatever the mare dye would cost. Serious answer is that I have not really looked into it. Dunno what a pure black nightmare looks like dyed vs non pure. So would have to take that into account first. I got lots of mares tho. Should have a good pure or non ready to go
