So we went for fun and see if it was doable to 3 man Citadel of flames third path. It took us 45 minutes and a few fails. No food, no potion (the one you see are actually undead ones xD).
And even though we had somewhat of a trinity, after doing it, I think it can be done by pretty much any team of 3 ^^.

(it’s 45 minutes, missing the torches’ lighting… stupid recording program bugged on me. For you on low connection, the video was 1.2 GB before uploading. No idea if youtube compresses any.)
