Hmm, the Orgrimmar guards and Garrosh Hellscream are still only doing the same damage.
Did this work for you or...?
Hmm, there up by 3 or 4 damage, but the same thing happening. Pretty sure its not totally fixed for each creature/npc just yet. Should giving it some time and see what happens in the days to come. TC is known to take their time on things. Best thing you can do at this point till its fixed completely is to attempt to fix it on our own. Pretty much what I do now a days with my project.
