Common Courtesy with End-game Raids/Dungeons

[Tazo]

Am I being trolled?
woosh?

If I am, I'll take the bait.
@Kuwagami I do the freshly released content with FC mates and try to figure it out on our own. After that it is simply wasting peoples time to join a group and just go in blind.

I just don't get where these fabled creatures exist that gather together in a party of 8 and do endgame content(blind) after it has been out for a month or more.
