Won’t lie I have no idea if this is well known or whether its new to remix but I’ll boost it either way
During the intro scenario for Isle of Thunder (Horde), when you mount up and fly over the Isle, if you have any movement speed augments (gems, talents etc) your mount will slow to a snail’s pace after 5/10 seconds and continue with a 90% reduction for the rest of the section. Only way to stop part way is to log out.
Retried multiple times and the same thing kept happening. So I removed all my movespeed talents and gems, and it worked fine first time
