I found this mob due north of the Trakanon zone line, along and slightly east of the broken north-south path/road. I also found a few in the north west corner of the zone, but that was pretty rare.
As a hot zone task mob, I find it to be highly undesirable, especially for a non tracker. They are not that common, and not set in any areas. Undead gorillas would be a better choice, as they have a fairly large level range, so I believe many levels could benefit from them instead.
Just my thoughts...
