Today I was all excited because I got my second part of tier 9, went to a dummy to test out the bonus, to my dissapointed surprise it is not working. Talked to a GM who confirmed it was not working and said they were going to fix it in a future patch, I asked him how recent but he said he wasn't allowed to say.
So for all you retpala's out there who's thinking about what to buy for your emblems, don't buy tier 9 because of the bonus.
