The ones you saw did not, true, but even those were only a token few who dared explore the rest of the world. These adventurers were but a glimpse of the population.
The whole population
When we finally get to explore to the whole island in World of Warcraft, we saw more variations, including that variation in anatomy. Pandaren long tails were available to pandaren females upon their release.
Worgen populations
Worgen have none such excuse. While Pandaren have been around well over 10k years, worgen have been on Azeroth for about 13 years. Pandaren have had the opportunity to breed and produce species like the tauren have, but worgen have not. If tails were to be added, they would be just that; an addition, and explained in a questline.
First it was: Pandaren have always had tails.
Then it was: Pandaren women werenāt in WC3!
Then: The Pandaren women in WC3 wore robes, you donāt know that they didnāt have tails!
And then: Well fine, they didnāt have tails, but OTHERS COULD HAVE!
These specific pandaren have tails in WoW when they donāt in WC3. They just added them in for fun because it looked nice.
Kind of just speculation though at this point. But even the explanation of selective breeding does not work because why do the males not have long tails?
This dude has some sort of mental health issues. He canāt accept the idea of people having different opinions, interpretations, or desires for how they play a fantasy video game, so he comes on here every 45 minutes to try and shout down everyone else.
Heās like an anti-vaxxer or something.
It doesnāt ācheapen the raceā if worgen get tail options. If your sense of value of the worgen characters in this game is based so firmly on the fact that they donāt have tails, donāt select a tail option when they have them added in.
To me it always made them seem incomplete, especially if we remember how they were done badly, and kept in this state for 10 years, only then they started to have a better treatment that would make them come closer to what they should have been forever.
This difference is impoverishing and is only justify due to the lack of resources in doing them the right way since launch.
If you like something incomplete, you can keep your worgen with all the defects.
I prefer more options to rectify something that can still be improved after 10 years of neglect.
Another defect in the conception of the breed that Blizzard missed and puts us in the same situation as the forsaken.
Why do some prefer to joke, and never give any suggestion whatsoever to enrich one of the few races in the alliance that is taking something that gives more options or choices?
If someone wants an orc with 4 arms, let them make a thread and postulate about it.
I will have the constructive action of not going there to oppose something like that for mere mockery or pettiness.
