I wish they wouldn't give so many of the black mounts silly glowing eyes. Or make a version with them and one without so players can choose. I was thinking of getting the black wolf but that put me off and now they're doing it to the elk too. Of course the elk will probably be absurdly expensive anyway, but it's still frustrating.
I might get the black sabre cat though. I've been thinking I could use a 3rd 'special' mount for my 3rd main character and I was put off the grey version because of the flashy gold armour, but the black version looks much better.
