I have like 9 uniques left to kill. From those there is Captain Dale, hellscream, khatun, torchligher and haxxor that i have killed more than once. In some cases even 3 times, yet they are not checked out from the list. This is really frustrating considering how long you have to search for them. So what's up with this crap does anybody know ?
The kill achievements are definitely bugged. I've killed dozens of champion subjugators, but the kill never checks off under "We Are The Champions". Fortunately, a re-work of the achievement tracking code is scheduled for 2.1, so with any luck that problem will vanish quietly.
