Hotfixes have already been rolled out to correct this, as noted in the latest hotfix blog, but windwalker monks enjoyed a brief, rather confusing, night of
crazy DPS. It should be noted that deliberate use of this bug would most likely have been considered exploiting, hence why WoW Insider isn't in the habit of reporting these things until they've been dealt with.
The bug was ostensibly called by combining two abilities together:
Rushing Jade Wind and
Spinning Crane Kick. The former gives the latter a multiplier, which is supposed to be around 30%, but appears to have had at least a couple of extra zeros accidentally added to the end. As can be seen from the header image, windwalkers were posting incredibly high DPS when using these two abilities together. This wasn't an isolated issue, there were various reports on the forums, as well as
videos. Another example can be seen to the right, from
Wowmartiean, in the raid finder.
WoW Insider readers will no doubt recall the
previous bug with retribution paladins, where Censure had a similar modifier problem, resulting, again, in some disproportionately high numbers. As we mentioned in our recent
patch 5.2 PvP round-up, windwalkers were due some buffs, but this seemed a step too far! Blizzard agreed, and for clarity, this is no longer in the game. It remains to be seen whether any action will be taken against anyone who is considered to have exploited this bug, but it has appeared and been hotfixed so quickly that, with any luck, it will not have had any major impact. As Blizzard
noted on twitter, they ran rolling restarts to repair this within a very short time of its occurrence, and PvP Developer Brian Holinka
noted that a fix was underway shortly earlier.
