Players have discovered that the Windwalker Tier set is bugged and stacking Windwalkers leads to some very exponential results. This has now been hotfixed.
You can see in this log that stacking Windwalkers is VERY powerful right now due to a bug with their 4-set Monk Windwalker 10.1 Class Set 4pc. This debuff Shadowflame Vulnerability is supposed to increase the damage of the 2-set Monk Windwalker 10.1 Class Set 2pc for the monk only however, it currently applies to ALL Windwalkers in the raid is multiplicatively stacked.
This bug causes stacking Windwalkers to be exponentially more useful and leads to hilariously massive results as seen in this log. This bug seems similar to the Devastation Evoker bug that occurred during the Patch 10.1 PTR.
This bug was an issue with the Devastation Evoker tier set which scaled the damage of the Evoker with the number of Evokers in the raid.
