ok, i have to do something to get out of "site noob" rank...so:
Go to Outland, then to Nagrand. find that mob:
Gurgthock - NPC - World of Warcraft
he is marked on map.
Get quest from him then... and your quest is completed!!! so go get next quest, talk to questgiver (all quests from that npc are BUGGED, so all are completed)...there are 6 quests, all completed without doing something ^^
tested on 3.0.0 , 3.0.9 and 3.1.3 - working.
