Two of us did this one last night, level 31 warlock and priest. We just took the road north from Tarren, looking for yeti in the Hercular's Rod quest. Had to kill a couple level 34 ogres to get to the yeti, and going through the yeti took us west to a field outside Dalaran. Scouted out Dalaran and the internment camp with the eye of Kilrogg and decided to try this stone token quest.
It was a lot easier for us killing the guards than the yeti, so we cleared the perimeter and went in, cleared the yard, and found we had started to do our orange prison-breakin quest, so we kept on going. Cleared out the building, and then went into the buildings outside the fence. Had a very close battle with a level 36 mage at the very top of a building, but got the yeti quest, this quest, and the prison breakin quest done all at once, walking in one big circle.
We didn't have the red-shield/melee problem, maybe because we're casters. I used a succubus and corruption, agony, shadow bolt, wand on the guards. The succubus was useful in seducing them when we aggro'd more than 2 at a time. For casters, curse of tongues, corruption, shadow bolt, and just drained their mana while the succubus attacked them. We usually didn't draw more than 2 attackers, and mostly worked on one mob at a time.
The drop rate must just be variable. My partner had 10 stones before I had 5, but as we fought our way back out, I picked the other 5 up quickly. Of the 2 quests we were doing at once in there, the drop rate on this one was more of a problem than the difficulty of the "prison break-in" quest, so just had to be patient.
