As of this message date stamp, I was able to request, get, and complete this task as a level 95 without shrouding down.
Also, the Task Objectives have changed as noted by Temperance earlier:
Kill 4 Wolves 0/4 (Goru`kar Mesa)
Kill 4 Bears 0/4 (Goru`kar Mesa)
Kill 4 Diamondback Snakes 0/4 (Goru`kar Mesa)
Kill 4 Earthen Ooze 0/4 (Goru`kar Mesa)
Speak with Laurentiu 0/1 (Goru`kar Mesa)
Objective Info:
Minhoten scouts have been injured or killed by the wildlife in the area. Reduce the numbers of the wildlife. Snakes and wolves can be found south-southeast in Goru`kar Mesa. Bears can be found in the southern part of the Mesa. Earthen oozes are located in caves to the west of the Minohten camp.
