Careful Attack/Aura of Courage/ Lostmauth's Artifact Set Feedback Loop interaction lags everyone to a standstill.
This is a very similiar we had during SW testing on test server with the AD set and Burning Radiance. It all causes a feedback loop.
The average WOD dragon run high crit tank will only get 200 to 300 lostmauth set hits for example.
