Technically yes, but a part 2 was made automatically.
This has been said so many times, we know Genn is depicted as not having a tail in several other media’s, hence the clarification in that book, but that doesn’t necessarily mean that Worgen aren’t capable of having tails. Just that Genn specifically doesn’t have one.
It really just reinforces that it is completely reasonable to assume that the bipedal wolf like race would have a tail.
And to others, they would look better with tails as an option. Its completely additive and nothing is subtracted.
But in all seriousness, this really should be contained to the megathread.
