Guys this is a very small exploit(dunno if its working as intended).
If you are doing the daily, Vile like Fire!, in Shadowvault, when you use the drake, you feel like, "Shit this is ****ing slow what the hell", a thing to do here is to fly the drake while pushing it down to the ground, then it suddenly goes like an epic ground mount or even faster. This can make the quest even easier and faster.
Sorry if its a repost, searched for the quest name didnt come up anything!
