Something that my FC and I have noticed ever since we got Haukke on farm:
The difficulty of the bosses seems to be somehow linked to the Wood Wailers that you can save in the beginning. I don't know if its their overall stats or just their HP, but if you fail to save one of the Wailers all the bosses seem to get some kind of buff.
This wasn't a one-off event, but I'll relate the most recent from the other night. We did four Haukke runs. The first one was flawless, zero wipes and a 29:00 completion time. The second one one of our DDs DCed and we failed to save the second Wailer at the start. We then proceeded to just BARELY clear the first boss after a very hard fight. We always kill him before the giant skeleton appears, this time we just couldn't do it. We then wiped 4 times on Ash because his adds seemed a hell of a lot stronger. Then we wiped three times on Halicarnassus because the 2 Maidens seemed to have too much HP.
Edit: The two runs that followed we again saved all the Wailers and aced all the bosses in one try.
