just a quick note for anyone who's never tried it. 5 party members does not = 5 star rating lol. tried the 10~ dodo leve from ul'dah with a 5 person party, all 12-15 rank in their respective jobs and we got murdered. couldnt even down a single dodo. they were smackin us for 400+ and of course you fight them in pairs so yea.... dont do it! or do it at your own risk =P
Just did this same quest tonight with a group of 3 on 2 star and it was a bit rough, we got through it without trouble but there were a few moments where we got a bit low.
