Died earlier to this quest at the Southern tip of Tanaris. Researched it online and multiple sources (guides/ videos) showed that 5 level 45s spawned when you interact with the quest objective, which I figured my 48 warrior could handle just fine with cooldowns and a health pot. Shortly after the 5 spawned, a few seconds passed and another wave of 5 spawned so I was swarmed by 10 and died. I went back to youtube and saw some other people try the quest and they had 10 spawn as well, so apparently it can be hit or miss with the number. Not sure if it’s a bug or just a weird feature. Anyway, definitely unsafe and not worth it, especially because of how out of the way it is.
An old bug, since launch of Classic.
