...for the umpteenth time: it's called collective punishment. Yes, you have to think about others; no, your actions don't only affect your own self. It's an MMORPG, you share the world with actual flesh-and-blood people on the other ends of the line. It's always been like this, it just wasn't apparent because most people didn't give a damn and just did what they felt like doing. Caused a lot of issues, hence the system now.

Yes, there is ready check, please use it. On a more general level: there's communication, please use it. This is a social game, don't isolate yourself. And especially if you're going for something as a full premade party...how are you not aware whether your FC/LS mates, your friends are ready, to begin with? Don't you guys...you know, talk? Consider how much time you have, make sure you're the class/job you want to go as - how so many people fail something as simple as this three times, so quickly and so often, it's just beyond me.

And last but not least, why is everyone acting like 30 minutes makes the world end? It's typical DPS queue time (which might be even much longer, especially now with everyone ninja-ing). Besides, there are tons of other things to do in this game outside the DF as well.
