they are either going to be farming all day with that no deaths bit or not farming a damn thing really

things like that are usually said just to ward off the feint of heart. but content like bismarck ex can be really hard if your party is not pulling it's weight. you can put an item level of 170 required on there and it won't matter if your dps can't dps worth half a crap. or if your OT plays like they are colorblind.

join an fc to learn fights, pug them afterwards if you still want to do them. if you don't want to do that, you don't really have any other choice but to study the content and make your own groups.
