My Unmade killed counter is not ticking up despite actively hunting them, making War pantheon almost impossible, which then locks out 2 others. After testing its not just dis-counting the dungeon unmade but also atleast some repeatable ones in Old Rozan. As a result I suspect you'll have to be lucky & persistant at Old Rozan to get 30 kill count from just a few out of over 20 enemies, massively slowing things down.
