The best line of dialog in the entire game.

[BlueMage]

[Mysteltain]

Definitely got a laugh out of me when I read it. Buuuut, I'm gonna have to give it to Slafborn's comment about our playing-habits. I'm paraphrasing a but, but the gist of it is that he says we're all "too busy hunting for tomestones and relics instead of helping the Adventurer's Guild" and how he wishes all of Revenant's Toll would "look more like the front of Rowena's shop" =P

[Kyan]

I laughed too, at both those comments! There are some gems in the dialogue for all the new content added!

[Nialle]

I also loved how they tied in the inconvenience of Vesper Bay not having an Aetheryte into the lore.

[Artamie]

My vote is for "A gentleman is, rather than does.".

[Niniyo]

I swear, if I painted "CERTAIN DEATH" on one door and "LIMITLESS WEALTH" on another, nine out of ten adventurers would go through the first, and the other bloke wouldn't be able to choose, on account of bein' Ul'dahn.

This is my favourite quote. Oh Momodi >w<

[Mahri]

No, the best quote is anything containing the word "gobshite".

I love the localization team so much.

[Urthdigger]

There seems to be a lot of poking fun at player habits. They note how nobody does guildhests, and the Sunken Temple of Qarn has developed a reputation as a deathtrap (Given it's the first real difficult dungeon, with bees that were able to 1-shot a tank before 2.1, and a boss that inflicts Doom, the reputation is warranted)

[Wadoka]

I like the Thaumaturge quest line, about paying someone in magic-blasted bird flesh...

[Viridiana]

"My quarters, one hour."

On the other hand, I just started the MNK quest line. Having an NPC's dialogue actually be cut up with <babble> throughout was hilarious.
