Well for that people tend to just rush things, more so since most people have done the fights enough to know it by heart, as well as ilvl sync being high enough for them to ignore certain mechanics. Or believe they can. There are some video guides online if you wish to view them, though the only one you should really need to know is for the first 24-man raid, and maybe for the third one. The second one is easy enough even for newbies to not need a guide.

I would suggest asking in Alliance chat as well, you'll probably get atleast one new person who can help you out there, sometimes just a small spark can get that interaction going.

Also, if you DO intend to do the 8-man raids I would suggest looking at the guides as even with echo most of them are much harder then the 24-man raids. More so the final part of each Coil IE T5, T9 (moreso this one), and T13.
