Just trying out the blackwood collectors mount for myself, and woq its bad. Being somewhat familar with khajiit (living in one of their towns) and fond of senches.. the thought of why any senche would have its tail on fire is the most laughable thing, its a joke. Then when you actually ride it, its beyond silly.
Given these are the only new cosmetics released from eso that i've seen other players wearing... i can't imagine how many kittens this is killing for new players... getting a cat mount with its tail on fire.
I know cosmetics are somewhat sacred once they've been released for money since someone, somewhere would like this, but please put its tail out somehow. This would be eso not taking itself seriously.
Good luck.
