I'm on a PS3 and I have a laptop next to me, everytime I'm about to run something new, I google it. I read up on the fights. This by no means makes me a pro, but I have some rough idea of what to expect and willingly share this information with other people. I don't say anything, but it's starting to become a needed MMO social norm, sort of like saying "please" and "thank you", that you take 5 minutes out of your day to skim the info on the dungeon/fight your about to do as a courtesy to other people.

The dungeons are timed, and I'm sick of failing Duty Finder pugs because we ran out of time explaining shit to people who clearly have access to the internet. We're not the dicks for getting frustrated, you're the dick for expecting a detailed explanation every time you run something. "Well you were that person, too, once". YEAH. TIL I REALIZED WHAT A DICK I WAS BEING AND STARTED USING GOOGLE
