What is the hardest dungeon in the game?

Your experiences in Lower Guk would vary wildly based on your class. For a monk/warrior/SK/bard I could understand hating it. I main'ed a paladin during the first few expansions on live, and Guk was absolutely the easiest dungeon in the game for me. When Velious hit and we got IoN it became even easier. The only complaint I ever had about that zone were the goddamn bats that would break your IvU. Between Pacify, anti-undead spells, and stuns for the casters, a Paladin could start soloing there at 40 or so and never look back. Cashing out on loot there was always a good way to make money as a class that couldn't kill Hill Giants, too.

I know they're raid zones, but how come there's no mention of PoFear/Hate 1.0? I remember several raids wiping because you couldn't even zone in safely. Fear was the worst for that shit, too. Zone-in meant killing 10-20 mobs because they'd keep adding as you fought. And in Hate 1.0 they would just agro through the walls out of nowhere.
