They do work with the lore, and you plus another individual had proved it yourself when attempting to counter me. Their eyes change color depending on the magic they interact with. That has been established lore for years. Some individuals, like Shadow Priests and Warlocks interact with Void magic. That too has been established lore for years.
Worgen have never had tails, and they never will. All instances of Worgen since their introduction have been without tails. All playable Worgen are Humans (and the originals being Elves), and the curse simply added onto their current form by modifying their base appearance. It did not add any additional appendages. Original concept art is non-canon, and so is Hearthstone if they were (or maybe already have) to add a tailed Worgen there.
The Pack Form argument doesnât apply because they are two entirely different forms.
The only likely reason Worgen would get tails would be if a tailed race was given the Worgen curse, as the tail would get modified durning the transformation. If you want tails, advocate for that or instead request Saberon as a playable race.
It was a deliberate design choice to not give them tails. Even more deliberate in fact as some original concept proposed the idea and it was denied. Additionally a Worgen was supposedly given a tail by accident in a novel and board game, and those too were quickly fixed by Blizzard shortly after the mistake.
Worgen are based off Werewolves which in MOST occurrences are tailless. Worgen are also a human/wolf hybrid that leans to the human side, even more since they are not feral (in terms of the ones that are playable).
Not every âanimal based raceâ needs a tail.
Being a Worgen is a curse, and transitioning between Human and Worgen is simply tapping into that curse in a controlled way. Itâs not the same as a Druid shapeshifting. They are curse humans, they arenât descended from wolves.
Oh and if you want an even further point to finish this up, Christie Golden herself (a senior writer for World of Warcraft) has stated they do not have tails.
