Apparently the Patch 1.12.1 will change the way mounts are handled. The price for mounts will greatly reduce, while the skill to learn riding – 75 for bkue mounts and 150 for epic mounts – will cost 90 and 900 gold. No worries, if you already have an epic mount you will learn the riding skill automatically, once the patch goes live. Read more about the upcoming patch here. There are no patch notes availlable, yet. I will give an update when they are published.
