I’m dividing my picks based on expac because I’m taking account of the way our toolkits availability impacts the dungeon experiences.

ARR - Aurum Vale
Cheese puddles, hard hitting mobs, awkward lv sync that locks you out from crucial abilities, and boss gimmicks that players actually have to pay attention. It used to be even harder in the past which is probably why you’d see some DF folks straight up bail out if they get this one via roulette.

HW - Dusk Vigil
HW has no real ‘hard’ dungeons but this one is where I’d see DF folks fails more than the rest. I also tend to get this one as a healer who still yet to learn some more of their useful tools at this level.

StB - Bardam’s Mettle or The Burn
Bardam’s difficulties mainly comes from wall pulls. It’s merely a shadow of its past glory at this point but it can still get spicy when one or two players are playing sloppily.

Mist Dragon in The Burn is a bane to a good number of DF folks. That boss alone accounts for most of the dungeon’s difficulty.

ShB - Holminster Switch or Mt.Gulg
Holminster has spicy first two pulls, but that’s it.

Mt.Gulg has slightly toned down wall pull difficulty compared to Holminster but all their bosses has one thing in common: quick, or straight up untelegraphed AoEs. This is also a bane to a good number of DF folks.

EW - Tower of Zot
Some spicy pulls, although not quite up there to Bardam’s or even Holminster’s degree. Punishing mechanics and rather abundant of quick AoEs to deal with, especially from last boss.
