I have absolutely no idea how I did this, but I had 50% speed boost without any buffs or mount except noggenfogger skelly.
This is how it happened :
I'm standing outside of TE, waiting for raid to start, when I drink a Noggenfogger Elixir - and out of suddenly I got disconnected, the EXACT second I drank it. When I logged back in, I had 50% speed boost.
I have no idea how this happened, but it may be useful for someone.
