So this thread has boiled down to:

Side A: Raid content requires prior research to save wasted time in duty finder
Side B: Shut up mom! I do whatever I want! No one tells me to watch a video or read a guide!
Side A: Ok then I will not party with you and waste my time when I came prepared and you did not
Side B: Elitist jerk!

ಠ_ಠ

For anyone on side B, please stop talking about low level dungeons or storymode dungeons when it comes to reading guides or watching videos. Side A is only referring to end game raid & progression content. Nobody cares if you didn't read a guide or watched a video for Cape Westwind or Praeratorium.
