They're cool but I feel the tail... err... situation, would make them un-implement-able.(?)
Considering this may only be possible in a future game, who knows how well the render will be.
Also I had an idea with the vampiric situation, being infertile and unable to age. As we saw in the game curing vampirism is possible, and it would be an interesting weapon to well placate them.
As for the race, it would be interesting to play as them and I will definately give them a go
