Correct.
The debuff only used to apply to folks who left voluntarily but it seems there was a lot of abuse where the person who wanted to leave the dungeon/raid would simply exhibit bad behavior in order to encourage others to remove them. That way they could jump out of the group without being penalized.
I’m sorry, Aga, but the debuff will need to tick down normally and as you did not remain in the instance, you do not qualify for any of the rewards that you may have received. Our staff would be unable to assist here.
If you wish to see a change to how the debuff system works you are welcome to post in the Dungeons, Raids and Scenarios forum. Understand though, this has been in place with a good deal of success for a while now, it is unlikely to be removed without a lot of player support and a better idea to take its place.
