I don't know. What? Glad mounts can also be netherdrakes that were armored. There are two sources for WOW Classic TBC Gold netherdrakes.

The skytongue mounts as well as kara mounts were also offered. With the exception of the kara mount that was a horse with fangs, the other mounts were unique models.

Ok look I feel you. For real I get it. The TBC reps also feel important. When you've done it you will get all the heroes you require. There are some items that can be extremely valuable when you repeat the process and cheap WOW TBC Gold that's why some cannot be replaced easily.
