There are also people who wants to rush the dungeon, I had my share of frustration of people who just keep rushing at the boss while we (new players) are watching the cutscene and the boss will be sealed from us (watching people slay a boss is not amusing to say the least).
But I was so frustrated beyond measure when I reached the last two quests, the most important of all, when I found out that people farm them with new reqruits for the 100 tomes bonus. I requested politely from the start to be allowed to watch the cutscene but to no avail, the kept rushing. Cutscenes flawing one after another not knowing why/where/who. TOTALLY WRECKED THE ENDGAME STORY!!!.
Oh and thinking of using party finder to find people to go through slow and easy, well it is rare for people to join in those so the invitation will expire and will lead to more frustration.
