Durnhold Keep inside Old Hillsbrad Foothills dungeon

Doing loremaster, currently inside Old Hilsbrad Foothills dungeon. Burnt the building’s with the incendiaries items. Killed the first boss. Gone into the basement to find Thrall for hand in. Why hasn’t Thrall spawned after I have done the required steps to hand in quest? Where is he? Why hasn’t he spawned where he is supposed to spawn after you do the first objective? Can’t even contact a GM anymore to fix issue. Ive got 48 quests to go in Kalimdor. pretty agitated at how sparse the quest line actually is. Cleared Azshara, there’s like 4 quests there… wow. An unfinished zone in a published game. Can’t find many more quests even though I’ve been everywhere man I been everywhere man I swear now doing caverns of time quests which are TBC but they count as classic vanilla quests. Where’s the rest of the quests? far out blizzard.
