On March 11, this hotfix was posted:
- Darkflight’s movement speed increase no longer stacks with Burning Rush or Burst of Speed.
Almost immediately, rogues started noticing. And it wasn’t just the worgen-only Darkflight-BoS combo — which had reportedly allowed worgen rogues to briefly experience run speeds of up to 425% — that had apparently been affected. Burst of Speed no longer appears to stack with any other movement-speed enhancing spell, including the engineering perk Nitro Boosts.
This, in and of itself, appeared to cause only a small amount of grumbling. Worgen players have long been able to stack Darkflight with Burst of Speed, giving them a huge advantage in select situations — for instance, as a flag carrier in Warsong Gulch. Establishing better balance, even at this late stage in the expansion, is hard to argue against, particularly when the change is ultimately such a small one.
Regardless, though not explicitly laid out within the hotfix, the change appears to be “pretty much” intended:
What may be less intended is a side effect: While Burst of Speed is active, rogues appear to be locked out from using any other movement-enhancing spell, including Sprint. This prevents a rogue from, say, hitting Sprint just as BoS is about to wear off to maintain their 70% speed buff without interruption. Instead, BoS must actually drop off, briefly slowing the rogue, before Sprint can be activated.
Whether this is part of the intended changes or not — and whether it’ll be tweaked or not — remains to be seen. But it looks like at least the design team is keenly aware of the complaints.
