When you’re affected by a crowd control effect in PvP, there’s an 18-second window for diminishing returns on further effects from the same category. Additional CC effects used on you while diminishing returns are active are reduced in duration: first by 50%, and then by 75%. Each CC effect resets the 18-second window to its full duration, and if you are affected by three CC’s of the same category inside that 18-second window, you will be immune to further effects from that category until the 18-second window has passed.
The lists below have been separated out into their specific diminishing returns categories. Each ability shares diminishing returns with the other abilities it has been listed with, and no others, except where noted.
Diminishing Returns Categories
If anything is missing or incorrectly listed in a different DR category than what it should be please feel free to point it out. I put this together to the best of my knowledge for 9.0 to update the previous post. w

Note: Diminishing returns on effects in the Knockback category operate differently than other diminishing returns. When affected by a multi-target Knockback effect, you will be immune to further multi-target Knockbacks for 10 seconds. This only applies to the abilities listed below; there are similar abilities, such as Death Grip, that intentionally do not trigger or suffer from Knockback diminishing returns.
