I just unlocked Dark Irons, and made a few to see how the animations and such are. Every time I did, I got Moira’s voice over and Wrathion talking over here. I haven’t tested it, but I suspect that’s the case with any new character. Given that it’s the first time making these Allied races, I actually wanted to hear it.
I know it’s not gamebreaking or anything but it would be a nice and easy fix to put in.
