It's not the class fluff mounts nerf that's bothering me. Those weren't intended to be as fast as they are. It's the purchased mount nerf that has me in a tissy. If I'm going to shell out multiple plat for a mount, I expect it to carry me somewhere. A possible solution I see, is if the mounts are too fast for the cost then raise the costs don't nerf the speed. They're really not overly powerful right now.
Nerf fluff mounts for all I care... keep purchased mounts the same or give me my money back.
