The question is: are players in duel considered elite or not? This question is crucial to us because there are many gears have the + elite damage and - elite damage taken, such as stormshield, stone of jordan, linatry of undaunted, all set armors (ik, inna, tal, zuni) can toll 7% -elite damage taken. And most important, many cool builds can be viable by taking the advantage of this mechanics. So Please, Blue, please hear from us, let us know the answer.
If the answer is "yes", then please list it as a bug, and tell us you are going to fix it.
If the answer is "no", then please at least fix the bug for Witch Doctors, because their gagatuar pet is not triggering too.
