I don't mind that people haven't watched videos. its week one. But for those who are so intent on being completely ignorant because that is "fun" for you. It is not fun for everyone else to let 3-4 people kill the raid several times while learning something we could have explained at the start. Simple crap like tank switches. In the past 24 hours ive had 3 groups dissolve before the pull because some primadonna off-tanks want to be completely blind and they leave as soon as I tell them something as simple as

" Tank swap on perpetual ray, Tank Add at A, Tank add at B, split damage for double rocket punch"

Simply saying that right there would save 3 maybe 4 wipes for the whole group. These people hide behind the guise of learning as their fun, but really I think they just like killing people.
