Fuck, I get what you mean,

. Just finished it last night, but holy shit that one's long. Biggest dungeon in the game? Definitely.
Sure, it's the Deep Roads, but was that really needed? Couldn't they just limit the Dwarven thingy to one area (as the dwarven thing is already rather long, with the whole political thing you need to struggle through as well), and use the Deep Roads as the final bit?
(Note that I'm not at the final bit yet - if it's better, don't say anything. If it's worse, stfu as well. In fact, just don't say anything at all,

)
