I roll on basically everything in dungeons/older raids because it's free FC points. With my FC running 3 airships and wanting to start up the 4th, we go through a crapton of points on ceruleum tanks alone, not to mention what we use on company actions. It's a fairly small FC, so we all have to work at earning points; we don't have the millions upon millions stocked up that larger FC's end up with. If people ask me politely not to roll on gear for a certain class, I'm happy to pass. If they're jerks about it, they can suck it up and pray to RNGesus. If I could only roll on one item per run, frankly I'd just bail after I got my one item, craft for half an hour, and requeue.
