There’s a bug with Timerunning and Travel Form(Grounded, Combat) that causes druids to be able to gain an uncapped amount of speed.
Steps to reproduce:
Play a Druid that is at least level 20.
Spec artifact weapon into Nostwin’s Impatience.
Enter combat.
Shift into Travel Form (goes into cheetah/stag form rather than flight form because you’re in combat).
Escape combat. [Whether by running away from the target so they reset, or just killing the target with white hits]
Point yourself into a corner and just auto-run into it.
Every time Nostwin’s Impatience refreshes itself, you gain another 20% speed beyond its normal cap.
It’s not particularly abusable since it is very easily broken [Trying to perform any action that would take you out of form, entering combat, failing to move during the refresh intervals for Nostwin’s Impatience…], and it takes a long time to get an appreciable amount of speed [It took around 33 minutes of running into a corner to get up to 10,000% movement speed, if it’s any indication], but you probably should fix it so people don’t cause the anti-cheat to freak out once Legion Remix hits Retail.
EDIT: This bug was not fixed with the update that came on 8/20.
