Wanderer's Palace sated my need for Endgame difficulty. The Giant Slime and Goobbue's were really hard the first time we did them; some of my friends are even still struggling with a certain mechanic of the Goobbue, lol. I haven't done many of the the others(aside from the story ones up to Brayflox), I do know that Brayflox actually had the boss get a little harder with a change to his poison pools.

Titan, as it stands, has been fun for me. I went with two Pick Up Groups and we kept wiping 'cause they'd get knocked off so I'm probably going to be running with my FC. I'm looking forward to the BCoB and all the other dungeons. I'm very pleased right now with the dungeon difficultly to the point that I'm smirking at all the "Too Easy" posts of the past.
