I never really got into end game on XI (when I did, the strat and such existed for awhile, so not really hard per se when joining a dozen or so that know it by heart) but when running CoP with a group of old EQOA friends, we ran into the airship fight. That took us a few tries and I, at the very least, found it to be one of the more stressful ones for that expansion. I've heard that fight is a joke now since they canned the level cap on those fights.
