Hi Empyrean, I'd like to suggest to yourself to give it a try. Set your level to, let's say, 16, give yourself some decent gear (take a look at Atlasloot and choose from there) and try to complete this quest inside a cave in Darkshore. I personally think that tunning down the global respawn rates for standard MoBs to a point that that quest is soloable would do the job.
Keep us informed of this matter, since it's the only major downside in Medivh nowadays.
Thank you in advance.
